Audio Routing issue - EVO 4G Q&A, Help & Troubleshooting

recently i have been experiencing an audio issue that only seems to be fix itself after a reboot. hopefully someone here can point me in the right direction for further troubleshooting/debugging/resolution.
on occasion i use the headphone jack to listen to pandora. if a call comes in during this time the pandora audio stops (as it should) however, i cannot hear the caller via the earpiece or headphone jack. the only way i can hear them is if i unplug the headphones and turn on the speakerphone. once the call is ended the audio sometimes will resume from the headphone jack, sometimes it will not. the behavior is the same even if manually exit pandora and unplug the headphones. it is also the same if an incoming call does not interrupt the pandora session.
similarly, if i am listening to pandora on the rear speaker and i plug headphones in, i get no audio in the headphones. if i unplug the headphones the audio does not return to the rear speaker.
visually, the headphone icon in the notification bar comes and goes as you would expect at all times. i am running a sprint lovers 2.2 rom. this problem only recently started, and i don't believe i had done anything to cause it like installing new apps or anything of the sort.
can anyone help me out?

[Q] Co-Pilot voice output acting funny on my Desire

I am pretty new to Android and still trying to get all the grips on I need. As of now, there is one thing that really bugs me badly.
I use the device for Sat-Nav driving a lot, I have a semipermanent installetion in my car from my previous smartphones. Basically just a power feed and a 3,5mm Jack that come out of the dash panel where the device holder is mounted. I recharge plug in for recharge as needed. The audio jack goes into the device, from there to a so-called Fastmute box behind the dash which is connected to the stereo head unit (the loudspeaker output cables running away from the head unit to be specific. The Speaker lines are interrupted by the box and just pass through whatever audio is being played back by the stereo. However, once there is current on the 3,5 audio jack (i.e. speech from the SatNav) the music immediately goes mute and you can hear the turn instructions in perfect quality through the car speakers. Once the signal fromthe satnav dies down stereo music comes back.
For my taste this beats most commercial, fixed systems.
Now, since I am on Android weird stuff happens.
On a first testrun shortly after I gut the Desire (which was o2 branded stock 2.1 at that point) I noticed that I do not get any announcements through the fastmute. Checked the jack, opened the dash to check internal wiring, retried a mp3 player. It's all good on that side. The accouncements come through the device speaker, hard to hear, easy to miss a turn etc. I do not why or how, but it seems that the audio routing takes a route different from other audio. This had me pretty much meh!
Well few days later, now with a ModaCo R8 custom ROM and Froyo I was hoping for good luck and gave it another whirl. Of course, no dice. When I plug in the jack of the supplied headset (which I assume doubles as a handsfree) I get the symbol for that in the upper symbol bar. When I exchange that headset jack with the regular 3,5mm jack the symbol looks different, but still vaguel like a set of speakers.
But now here comes the completion of the mindfaq... I had the SatNav volume at about medium (so barely hearble with driving ambient noise) when the phone went and I took the call through the Bluetooth Handsfree instaalled in my car and was distracted by the call (the car came euipped with the BT Handsfree from factory, so the stereo goes to "pause" and the conversation is routed into the vehicle speakers.. A few minutes into the call I suddenly hear a perfectly well understandable, clear turn instruction hopping into the phone conservation. I was extremely intrigued and was hoping that I discovered that CoPilot can route instructions either into A2DP or more likely emulate a "call event" that results in routing the audio into the according BT profile.
However, after that singularity I tried reproducing this for a god part of an hour, driving a route that forces many instructions from the SatNav, all the while calling my own answering machine fo have an connection established.
Sorry for the lengty explanation. Questions:
1 Has anyone ran into this before? What was your solution? Bear with it, switch SatNav software, avoid listening to music in oder to not miss any turn directions?
2. Is there a hack, hidden configuration that would enable me to _force_ this audio routint into the direction of the BT Handsfree, making it think it is an incoming call?
As a fellow co-pilot user I share your frustration.
You will probably find that it's nothing as technical as it not routing to bluetooth or whatever.
Co-pilot has a nasty habit of messing with it's own volume setting when a headset is plugged in. It tends to reduce itself down to zero without notification or cause. You would try to reset the volume, but firstly, it wont go more than a third of the way up, and secondly, it will simply jump back down to zero again on it's own.
They know about this issue and their response is not to use it with a headphone jack!
It is rather annoying!!

No audio... help!

So this morning, after my usual flashing of the latest Cyanogen nightly, I noticed that my Inc was no longer putting out any audio. Without thinking twice I recovered the previous nightly, but I'm still getting no sound from notifications/ringtones, music or alarms. Thanks in advice for any suggestions.
Sent from my ADR6300 using XDA App
Update: I plugged my phone into my stereo and am getting audio again, but still not from the phone itself when I unplug it again. This leads me to believe it to be a hardware issue, which is probably not an easy fix. Should I start looking for a new phone? I use it as my alarm and I need to hear my ringtones because I don't always feel it on vibrate so it's not very useful to me now...
I'm seeing a similar behavior. I have audio until I use a BT headset. Once one has been used, I lose all audio from the phone speaker (even after the BT headset is disconnected). I'll have to try a wired headset to see if the audio is redirected. Only a reboot will restore my audio from the phone speaker. If the headset supports A2DP, I lose all audio even through the BT headset.
Does a reboot fix your audio?
Reboot does not fix my audio. I figured out that it is a problem with the speaker itself, which is very easily replaced http://forum.xda-developers.com/showthread.php?t=799592
My audio works fine when plugged into my stereo or headphones, but is intermittent from the speaker. Apparently Incredibles are known to blow speakers?

[Q] Audio issues

Was on EH06 leak, stock rooted. Use car dock, bluetooth, and headphones often during an average day. At some point yesterday, my phone's audio became broken. I've since Odin'ed back to EC05, and its still the same issue. Most of these symptoms lead me to believe the phone always thinks there are headphones plugged in. BTW, I have tried plugging in several different headphones. Certainly seems like a hardware problem, so I'll try Sprint without insurance to see what they'll do. Appreciate any input.
What does work:
+When I get a call, the phone actually rings out of its speaker.
+Volume up key beeps out of speaker
+All audio seems to work with 3.5mm headphones connected
What doesn't work:
-In-call, speaker-call button is grayed out, unavailable
-No in-call audio. They can't hear me, I can't hear them.
-Same problem in-call for bluetooth.
-Music won't play through speaker.
-Music won't play while in car dock.
-Changing ringtones in settings doesn't play the ringtone I select (through speaker)
-When I plug 3.5mm headphones in, I'm sometimes prompted for voice search, and sometimes it automatically begins dialing a recent call.
Take it to a store
I would suggest taking it to a store and show them while being kind. Don't do telephone support because they will probably say "No insurance, no dice." If you catch the tech on their good side I'm sure they will help you out. It may be as simple as a busted contact in the jack. My friend's iPod had a problem like that.

VZW Nexus headphone recognition - App for that?

Not sure where or what to search for on this issue but it's been killing me with my Nexus for the past few months.
Coming from a couple of HTC phones one thing I really liked about them, which might have been Sense feature, was the phone having two completely separate audio volumes one for when headphones were plugged in and another for when the phone was hooked up via Bluetooth.
My problem is I listen to music very low with headphones at work, then unplug them before getting into my truck, automatically hooking up to the Bluetooth to stream and the volume stays at the low headphone volume. To hear it over truck stereo I need to turn the phone BT volume all the way up. Fast forward to when I sit back down at work to listen to music, my headphone volume is back to the last BT volume or maxed out. Just a real annoyance and find it hard to believe this is the way Google designed it and has nothing in place when I'm having an off day and don't manually fix it before I listen to my headphones again and blast my eardrums like I did yesterday.
Is this how the Nexus should handle BT and Headphone volumes? Is there any kind of fix for this?
Thanks in advance

Using Audio out jack and Bluetooth at the same time causes problems...any solution

Anyone have a solution for this one?
I have a 2008 car with factory installed Bluetooth phone interface. The Bluetooth is ONLY for the phone, not music. The car also has an aux in jack for the stereo. (Know where I'm going with this yet)?
Yesterday I was listening to music using the 3.5 mm jack on the phone, and it was also connected by Bluetooth to the car's phone interface. A call came in. The stereo automatically muted like it should but when I answered the phone I couldn't hear anybody there. After 30 seconds or so I hung up.
Then it dawned on me, with something plugged into the 3.5 mm jack, the phone audio may have been routed through that jack instead of Bluetooth. BUT the car assumes that when a call comes in you want the stereo muted so it kills audio from everywhere except Bluetooth. I suppose I could have reached over and unplugged the 3.5 mm jack, but that's inconvenient when I'm driving.
So, the question is, is there any way to set up the phone to always route phone call audio through Bluetooth when Bluetooth is connected?
I have the same issue.
I listen to music in my car via a cable from the headphone jack to my car stereo's aux in. If I get a call over bluetooth, I can't hear anything. If I unplug the cable on the phone side, I can hear the person on my car speakers, and the caller can hear me via the car's mic.
Are you using the stock firmware or a custom ROM? If it isn't a problem on a custom ROM then perhaps it can be fixed. It's very annoying -- my 3-year-old HTC Hero could do this, why can't the S3?
I was told by someone with a different version of the S3 (an international one) that this isn't an issue on their phone.
I'd love to find this out while I still have time to return the phone.
I'm going to try building a "car adapter cable" that feeds audio out the USB port to see if that works, Instructions are in this thread:
http://forum.xda-developers.com/showthread.php?t=1395173
That could be one option. Still seems pretty lame that we have to come up with workarounds for this pretty basic problem.
And I'd love to hear from someone running a custom ROM to try and figure out if it's a hardware or a software issue.
