Pandora blocking GPS? - EVO 4G Q&A, Help & Troubleshooting

I was just wondering if anyone else has come across this issue or heard about it...
I am running CyanogenMod 2.2 Nightly (7-31-2010) with SnapV3 Kernel. I was just out driving while listening to Pandora through bluetooth. I happened to try out google navigation whilst doing this and I noticed that I couldn't get a GPS lock. The navigation app just kept saying that it was looking for GPS.
After some playing around I realized that if I turn off Pandora the navigation app works perfectly, but every time I turn on Pandora I either get the looking for GPS message or my position will not update.
Thanks for any input!

It's been known for a while that you can't listen to music (over speakerphone speaker using any app) and use GPS perhaps bluetooth suffers the same flaw?
If you download GPSTest then start it and open pandora, last.fm, local music player, etc and then hop into GPSTest really fast you'll see the phones unable to find GPS satellites.

Ok, I'll give that a try. Thanks for the info!

I've been working in other cities where I need the gps to get there and want to listen to pandora, so after I ran into this problem, I started keeping a nandroid of a 2.1 rom....

Just came back from jog and yours was the 1st post I came across, strange because this is EXACTLY what happened. Listening to pandora in the back ground Endomond gps tracker kept pausing, this is the 1st time that program has ever had an issue so there is conflict somewhere.

Well, I have played around with it a bit more and found that playing pandora through bluetooth does not cause a problem. I only run into the issue when using the phones speaker. I'm not sure about headphones though, I havn't tried that yet as I dont really have the need for them.
Of course there is still a problem with the navigation app turning off pandora every time it gives you audible directions. To stop this I just mute the navigation app and everything works well together.

I just run into a similar problem this morning
I'm running the leaked 2.2 build from last weekend.... before froyo, I could listen to pandora and use google nav all while plugged into my car stereo via aux jack.
now, when navigation gives a direction, it pauses pandora and you manually have to go back to it and press play
sooo annoying... anyone else run into this?

Order of Operations Counts, I think
I ran into this issue both with 2.1 and now 2.2 on my Evo. I'm not sure who the culprit is, but I've found that starting navigation, letting it acquire the GPS signal, and then launching Pandora works fine. If I do it the other way around my GPS signal basically dies.
Another interesting quirk I've noted is that if I start GPS first, but then Pandora.. my Nav voice will play through the speakerphone while Pandora plays through the headphone jack. If I start Pandora first, then Nav, they both play through the speakers.
I think what it may be is if Pandora starts/is caching while the phone is trying to startup GPS and acquire a position. I'll test it more during my drive home tonight. This has to be a software bug on side or the other. (Maybe it's google's ad software in Pandora trying to grab GPS for location specific advertising lol)

I was directed here http://code.google.com/p/android/issues/detail?id=9569 yesterday when I brought up the same issue on a different thread. It's an issue with android itslef. Looks like it kicked in at the 1.47 ota, prior to that, the audio would go right back to playing pandora or whatever after nav told you to take a left.

Major BUG with GPS and audio playback possibility

I was using GPS navigation on google nav and playing music through the HTC media player and GPS signal wouldnt stick if i was moving, only if i was standing still. Something is preventing this multitasking. I need someone to test if it is just me or my ROM or these specific apps. I am running fresh .2 ROM btw.
UPDATE
GPS breaks when playing music through the external speaker. The signal will be lost, or really spotty until you stop playing music. HTC has not commented on the issue. Does anyone know why this is happening? Is it possible to fix?
yep i am using stock unrooted evo and i get same problem i was playinf music thru stock player and go to google nav and it wont find gps signal after pausing music it finds signal them i turn the music bak on and it looses signal
Haven't tried the stock music player, but I listen t
o podcast all the time while using the gps.
i think its a bug in the htc stock player i tried same thing with doubletwist player and get no issues
edit
i got lost signal on gps also with doubletwist now seems like a bug with google nav
Could you post your ROMs if rooted and also has anyone tried Sprint Nav? I will go and grab a sprint nav apk and test when I get a chance. This is very inconvenient and I am curious as to why it isnt working.
Uhhh, no problems here, playing mp3 from SD card using stock music player and got a GPS lock in a matter of seconds.
Latest radio
fresh .2
-Edit- Mine works sometimes but mostly doesn't, so yeah bug is present
anyone hear anything from htc about this, posted on their site and twitter and didnt hear anything, maybe i should call about this issue.
I don't use the stock music player app for anything but I experience this exact issue when trying to use pandora and the GPS. As soon as i shut pandora off it picks up signal again.
NEW FIND, any app, GPS and MUSIC through the speaker causes GPS signal to be lost. It works while using headphones but not the speaker.
Wow, is this a hardware or software issue?
You know, I actually forgot about this for a while, there has been no official word on this bug, and I havent heard anyone knowing why this happens.
I never even thought to try running my gps without music, I just thought it had a very crappy gps antenna or something. I have yet to try it without music to verify this as well, but tomorrow I probably will test it out.
Just a wild stab at the dark, but maybe the magnet in the external speaker interferes with the GPS antennae? Not too sure about that though....
Hmmm, would be interesting if the placement of the speaker and the GPS is the actual problem, I really hope not though. The problem doesn't occur when the GPS app uses the speaker or you get a notification playing on the speaker though, maybe the duration is short enough to not loose the signal? I emailed HTC about this issue, didn't have time to call them about it.
I can verify this, did a two hour trip last night and didn't lose the signal once with the music not playing.
Yes, it's because of the speakers
This is a funny problem. Something about the speakers is interfering with the GPS reception. It's not just that the speakers are on, but how loud it is. The louder the sound, the worse the reception.
I'm running the stock ROM. I used GPS Status and the stock music player. I played a song that is fairly constant in loudness, and noticed that as I turned up the volume, I would start loosing GPS satellites, and then as I turned the down the volume, I would get more GPS satellites.
Update: I tried the same test out on my Hero, and it definitely doesn't have the problem.
Ha, HTC already knows about it. And it doesn't look like they're gonna do anything about it, and this guys reply probably explains why my car charger takes forever to charge my phone.
Dear "My Name",
I understand that the GPS Signal will be lost is you use your device GPS with Music playing. As the device pulls more resources from the battery, the phone may become warm. The device has a built in sensor that registers the amount of heat the phone is generating and will shut down some features as the device heats up. Normally the Charging port will be turned off first, then the various radios will be disabled such as GPS, Wi-Fi and Bluetooth. If you are experiencing an issue while using multiple features of the device at the same time, I recommend that you stop using one or more of the programs and see if the problem persists (As you have). I do apologize for any inconvenience that you may have experienced.
To send a reply to this message or let me know I have successfully answered your question log in to our ContactUs site using your email address and your ticket number "My Ticket Number".
Sincerely,
Jeffery

If that's indeed the case, one can try underclocking to prevent the heat buildup.

Nope, HTC is just throwing something silly. What they describe may be true, but playing music doesn't instantly generate heat, nor does that heat instantly disipate once you turn down the volume, or plug in a headset.
As I tested above, you can slowly degrade your reception by turning the volume up slowly. This is clearly a different issue, and it is a reasonable inference that there is some sort of interference between the speaker and GPS.
Also, if HTC insists, you can prove them wrong by keeping the phone plugged in and showing that it is still charging the battery even when the GPS looses signal.
I experienced a series of reboots on my phone this weekend while driving and using the phone via a bluetooth headset. Simultaneously I was attempting to use Google navigation. I typically could connect to my caller and then would reboot within 10 seconds or so. This happened three times before I was able to figure out that the GPS connection was a culprit and temporally disabled GPS while using the phone.
Lamest part and this isn't the first time this has occurred! On the original firmware shipped from HTC I had a few identical crashes that I have only now realized were because of this combination of GPS+bluetooth.
Right now I'm running a simple OTA update + root using toast's method.

[Q] google nav/pandora 2.2

ok with all the 2.2 roms i have tried if you are using nav and pandora when nav speaks pandora pauses but it doesnt resume play after nav is done speaking it used to pause pandora then resume playback i really need this to work i love to put it in my dock for navagation and stream pandora at same time is tehre a file i can edit to tell it to mute pandora when the nav engine is speaking the way it worked in all 2.1 roms and 1.5
No one
Bump

Have you tried an older version of maps, maybe the 4.40 update broke it.
no there has to be a file that i can edit that tells nav how to behave
It's happening to me, too, so it's not just you.
Some delve please help maybe look at stand see what the permissions were in 2.1

Try and see what happens with Sprint nav.

It's a known bug in 2.2
supposedly pandora is working on it
By the way Sprint bab works but it plays thru doesn't mute or pauses they talk over each other loved how Pandora would just pause and resume

Yep it's from the 2.2 update. Pandora needs to update.

thanks for the confirm, that's exacly how I remember it also (I can't remember exactly when the last time I used nav was before I went to 2.2)
The reason I posted the link though, was to show that it looks like it's been noted as a bug on android code, so I don't know if this is tied directly to Pandora. I'm thinking it's more of a bug with the nav app instead. I'm no expert though.
FWIW, I'm running the OMJ 2.2, and if i'm running googleNAV and playing a song with the native media player, it will pause while gnav give a direction, but it also won't resume play once the directions are finished. That would lead me to believe that the problems is not isolated to pandora....
I just tried to day with last tm and it works as should so I'd say its Pandora code that broke
Sent from my PC36100 using XDA App
It hasn't been working for me on Pandora or the HTC music player...Such a small detail is going to cause me a traffic accident soon...I just know it.
+1, this happens to me with music player also, a big disappointment after having it work in 2.1 and setting up a proper car dock with audio.
Also, I noticed when playing a movie in rockplayer you don't hear the navigation, and even after changing to the navigation app I wouldn't hear sound until I closed rockplayer and reopened the nav app.

loose gps when playing music on speaker

When i'm playing music off the sd card or pandora I loose gps in maps and navigator unless I have headphones plugged in.
I think it might be the speaker messing with the compass, but i have no idea.
I tried googling it, but all i found were a handful of people with the same issue and tons of people saying that they go running or do x or y and listen to music without an issue, but they're useing headphones.
Any ideas?
Same Problem
I have the exact same problem and it has been driving me crazy! I have tested thoroughly and I can use GPS for days no problems. As soon as I turn on Pandora or the Music app it instantly stops tracking and a few seconds later says sorry no GPS signal in this area (confirmed on Sprint Nav and Google Nav). As soon as I stop the music it pops back in.
Have you confirmed that the headphones corrects the problem? If so that may provide me a good work around.
Has anyone else found a better fix/work around? It is very strange!
My thoughts exactly! Ever since the Froyo update I've been having the same issues as well.

The magnet for the phones speaker interferes with the gps, that's why you can use headphones and gps and not have a problem

GPS
Thank you. Is there any work around?
Seems like a pretty bad/serious design flaw.
just using headphones, but **** this is annoying. I use gps for work, and I dont want to use headphones all the damn time. my g1 didnt have this issue so it's like wtf!
That is by far the worst handle I have ever seen. Congrats.
As far as the loose gps is concerned, have you tried tightening it?

How do I get navigation to play nicely with music on Froyo?

On 2.1 everything was just dandy. But after updating, everytime the raspy voiced Google Maps lady speaks, she pauses my music, but refuses to hit play again. 2.1 lady would resume the music no problem, on both the HTC player and Pandora. Anyone know how to fix this? I'm secretly hoping there is an option I haven't found yet...its a huge pain to swipe back in, navigate to the music, and hit play while driving.
Yeah this would be great I dont remember using it on 2.1 but do know that it worked on CM6 Froyo and now that I am trying some of the new 2.2 sense roms it is a very annoying problem.
hmm havent noticed, havent used gps and music at the same time, my car speakers broke and i already know i cant use gps and the phone speaker at the same time, will try to test this soon though, anyone have stock 2.2 they can test this on?
Pretty sure this is an issue with all 2.2's including CM6 and that is has to do with how froyo controls audio (it's listed on the official Android bug list). Confident a fix is in the works though, either from Google or the devs here.

It seems to be an issue with a bunch of streaming media apps, not specific to Pandora.

Do you have a link to this list? I'm searching for it.
It should be made a sticky.
Yup, just tested it and it stops your music. Happened within 30 seconds of starting the navigation. I'm going to look for an old version of Google maps and see if that does anything, this update was pretty big.
Also, anyone have an N1 to test this on?
*EDIT* Using 4.3 does the same thing, was hoping it was a simple APK update needed, but we might need something more involved than that.
Sent from my HTC EVO 4G.
Same issue with UK Desire since Froyo. Happens with both Copilot and Google Maps.
I read in a comment on the Android bug list that downgrading Pandora to v1.3 fixes the issue. Does anybody have an old titanium backup of Pandora 1.3?
I confirmed today that it happens with both Pandora and the regular music app on Fresh 3.2.
However, I recently was on a big roadtrip when using CM6 and it worked fine with the AOSP music player, but I didn't test Pandora.
Either way, it's extremely annoying. Missed a few turns because I just put nav on mute.

[Q] No notification audio over bluetooth?

Hi All,
I've noticed that when I'm listening to music or podcasts (via Rocket Player, Pocket Casts, etc. ) over bluetooth in my car, I cannot hear any notifications. The music/audio pauses briefly to play the notification sound, but no sound is heard. The same happens with turn by turn directions via Here Maps (haven't tried Google Maps yet, but I suspect the same issue would occur). Has anyone else run in to this issue?
Try the latest update released today: "Force output to be primary output when using BT_SCO."
Still the same issue even after the update, unfortunately.

Just thought I'd follow up on this in case anyone else is having this problem. For whatever reason bluetooth notification randomly started working for me a few days ago. No rhyme or reason, but I'm glad it's working now.
