[Q] Leedroid DSPManager not working with A2DP

Hi,
I recently finally took the rooting plunge and installed Leedroid 2.3d, mostly for A2SD and DSPManager.
I cannot get DSPManger to work with my Motorola S305 A2DP headphones - turning effects on makes no difference at all. I have tried rebooting, restarting the HeadsetManager service and force stopping and restarting DSPManager.
I checked logcat while connecting the headset and the line "Bluetooth plugged: " + bluetoothAudio as specified in the DSPManager source in cyanogenmod is not there. At the begginning of the log I see a bunch of unhandled exceptions to do with DSPManager 'leaking' IntentReceivers, which could be related as it is supposed to be listening for BluetoothDevice.ACTION_ACL_CONNECTED, especially since it seems to create a bunch of BroadcastReceivers at start.
Will anything break if I try to compile the latest version from cyanogenmod github directly?

Ok, after some experimenting trying to get the cleanest logcat I could I've managed to make it work .
It seems it doesn't work until the service is restarted after an effect is enabled. It also doesn't work when all effects are disabled and then one is enabled until the service is restarted. It must be a bug of some kind with the bluetooth system as this doesn't happen with wired headphones.
DSPManager is awesome, especially the Virtual Room! It even works for Dolby Surround/Pro Logic encoded movies (only really noticeable for Room/Large Room/Stage)! . I always thought that was what Dolby Mobile did for the Desire but never could get it to work. I think the effect is at least as good as DTS SurroundSensation UltraPC Headphone (who came up with that name?), and certainly better than the Headphone Virtualization built in to Windows.

[Q] low sound output on headphones

when i listen to music on my zenfone ,maximum volume is very low also music lags when using other applications,tried reflashing the firmware and other headphones but that didnt work any one got any idea?

two ways to get higher music volume on ZF2:
1) Turn off the equalizer in Music, that seems to help.
2) Get some different earphones, the Asus bundled items are significantly quieter than any others that I have tried. **Sorry, I see that you have tried others, but keep trying, I use Skullcandy and Jays, and both are much better**
With regards to the sound lag (its not just Musisc, it happens with calls and other apps too) when multi-tasking, Asus has been made aware of this (see the "Audio Issues" thread on Zentalk forum), and may, or may not be working on a fix....
Some people say that turning off System Sounds in settings reduces the sound lag, but I can't say that it has helped me. This is the single bug that most annoys me with this phone.

tried updating music fx plugin that came preinstalled to a newer version it improved the sound output a little bit,thanx by the way.

I'm on 2.19.40.20 and still have this annoying issue both on normal audio and speaker, which is always too quiet for any hands-free or outdoor use
Is there any workaround ? (rooted phone)
Do you think that Viper4android or whatever could help to raise the sound levels ?

Disabled MaxxAudio

(I own an Asus Zenfone 2E so I don't know if this will work with the Zenfone 2) I disabled (AudioWizard/com.asus.maxxaudio) and rebooted. Tada! Headphone output is a crap ton louder! Hope this helps! I also deleted the MusicFX plugin. Don't know which one of those worked but one of them certainly did!
This is what I disabled using NoBloat(Remove spaces) http: //i.imgur. com/NO7dvls.jpg?1

Having your headphones suddenly become more quiet than usual, whether it’s on both earbuds or just one, happens quite more often than you’d think. Before we discuss how to fix the problem of your headphones being so quiet, it’s important that we understand why it happens in the first place.
Here are the most common reasons why headphones become quiet:
Issue With the Plug or Socket (For Wired Headphones)
Issue With Connectivity (For Wireless Headsets)
Device Settings
Issue With the Audio File
Issue With the Headset Itself
Issue With the Ear

LG G3 No Sound at all

Guys thank you for this awesome forum i have managed to root many devices and do a lot of great things with the few phones i had, this time however is different i have the D851 LG G3 T-Mobile and the phone does not playback any sound, ill be more specific :
* Any phone music application doesnt playback the music, the app just sits there and doesnt advance in the seconds counter
*The videos do playback but the audio is missing
*due to the missing audio the phone freezes when trying to make a call
*when attempting to record video it comes out as error and does nothing
* when trying to input voice commands it does nothing
* sometimes when trying to change the sound profile the menu freezes going from vibrate to normal sound
* no initial boot sound
Everything else that the phone does works fine like but to put it this way the phone feels just like when we have a pc and the sound card drivers are not installed or corrupted somehow, im not sure if its missing the audio codecs or maybe something else was modified in the system itself.
I already used LG flash tool to restore phone to 30d and im currently trying to restore phone to factory stock 10C
UPDATE 10C or 10R not possible to revert to, gonna try 20E
Update 20E boots up phone but still no sound at all , it is like its disabled
Please help!!!

Hate to bump such an old thread, but been searching high and low, did you happen to find a solution for yours? Have a G3 that does the exact same bit right to a T, tried reflashing Marshmallow, rolled it back to Lollipop with LGUP, runs perfectly fine, sound and all functions were great for a while, and one day it stopped. Plugging in headphones, I see the headphone icon in the status bar, so it recognizes them, but it won't record audio, play audio or do pretty much anything that involves sound.

you can try using viperfx, maybe you or a guest touched the phone and set everything to zero, try that dude. i hope you fixed the problem

No sound, freezes and closes all windows to lock out screen
Currently own an LG G3 D-851 T-mobile. I bought it used and everything seems to work out of the box.
Noticed that there isn't any sound
coming out of the device so tried playing around with the volume levels. The phone froze; went back to lock screen. Unresponsive. After which i had to do a factory restore:victory: and it worked flawlessly.
Was curious if this could be hardware problem so i took it to repair shop.
I was told that the problem lies in the memory (power ic) might be corrupted. Anyone might know how its related to having no sound or video recording capabilities? Plus why it crashes when trying out the sound recording.

Cant use bluetooth audio

Hey Guys,
everytime i connect my fire phone (slim kat) to a bluetooth speaker, i dont get any sound out of it.
What i tried so far:
-used multiple bluetooth devices (car; mobile speaker; tv sound bar) with no success. Everyone showed the same problem.
- removed all devices from the pairing list
- visible to all devices
- wiped cache
- tried spotify and poweramp
-moved from cm11 to slim kat: the problem was solved for like 15 min. The sound then suddenly stopped without me touching the display (no sound then, but the music player continued to play)
Any ideas? I uploaded a video showing the problem. all i get from the speaker is a silent buzz, which i tried to capture in the video at 01:20.
Also notice the weird volume button at 00:57...it switches from the normal audio speaker to the bluethooth speaker every time i change the volume.

I hope someone can help me.

I had a similar problem on stock, turned out to be my wearables apps. Microsoft Health and Pebble time, kept disconnecting me from everything else. May be completely unrelated, but worth a try. I uninstalled those apps and it started working fine.

Thanks for reply, but i dont have any wearable apps installed on the phone

Cmon guys, please help me. I know a lot of you guys are really into this topic...

Random loud screeching/white noise when bluetooth is on?

Recently, my phone's started to randomly shriek with white noise and it scares me silly. I think I've narrowed it down to when bluetooth is enabled and playing music (spotify).
Has anyone ever encountered this issue or could suggest what solutions I can try out? I've rebooted my phone and I don't want to immediately jump to a factory reset quite yet.

I have an AT&T LG G8 running Android 10 (SW ver. G820UM20k.) I've also had this issue for some months now. However, while I have Spotify installed I am almost never using it; the noise occurs anyway.
My usage pattern when it occurs typically involves going between YouTube, Chrome, and Twitter apps, and occasionally other social media apps. Often happens when playing a video or audio in the background, but occasionally get the noise when dead silent in between apps too.
I've noted that if I stop what I'm doing when I hear it and immediately switch the audio path back to the phone (via the notification toggle,) the noise often occurs again but out of the phone speaker after a short time.
Now, I've not experienced any random noises the past couple of weeks, but haven't found a definite solution either. Searching the internet for "phone random static burst" or "phone making loud noise randomly" yields similar complaints going back the last few years, across different devices (and presumably Android versions.) Disabling/ force stopping Chrome was a more popular suggestion that came up, as well as fiddling with the Bluetooth codec in developer options. (I'd also suggest making sure all installed apps are updated, if the bug is indeed related to apps mishandling audio somehow.)
Given the range of system specs with these similar complaints, my hunch is the core issue may have to do with certain Bluetooth stack implementations just having problems in certain scenarios. FWIW I have my Bluetooth currently set to AVRCP 1.6 (Default is 1.4) and audio codec to SBC (Default is System Selection.) In months prior when I had the noise issue, these were set to default. My Bluetooth earbuds (Sony WF-1000XM3) prefer to default to AAC codec but do support SBC; I believe I haven't had the noise since forcing the system codec to be SBC only. If nothing else works, may be worth toggling that setting and hoping it fixes the noise. Good luck.
