I love Viper4Andoird and works like a charm on KitKat roms, however on Lollipop the problem I have is buzzing, stopping playback, hickups while playing songs (worse on FLAC songs). All the effects works as it should but the only thing is these errors during playback. I have tried many solutions (including the one from first post), but nothing worked so far :(

Thats why I use KitKat as daily driver, could not make it to work without sound issues on Lollipop...

I did what the op said and it is working for me on LP euphoria 01/29/15 rom. I flashed all three in order, rebooted, installed se-linux changer from play store and put to permissive. Checked in settings and I was good. Rebooted then opened viper and flashed driver, then rebooted. Opened up power amp and did what I needed in it and it works! Thanks a lot. Like someone else had stated, I wouldn't stay on lollipop for a while because of this, but now it is working so far like a charm Thanks for sharing the great insight!

After enabling the driver all sounds comes from the earpiece rather than the phone speakers. Did a bit of digging and this seems to be down to \system\etc\mixer_paths.xml. When comparing the file versions from the download in this thread to the One Plus default and CM12 version they are significantly different (100's of lines). So I suppose it's not as easy as replacing one with another? Any clue what interfaces I'm looking at changing to fix this? :eek:

Worked for me
I had the same issue, divers were installing repeatedly
But setting it to permissive made it to work
So what it this setting that I had changed?
And should I change it back when viper supports lollipop officially?

Yep! Updated it last night. IMO, it definitely produces a better sound than 2.3.30 with earphones on the 05Q build. I'll try it thru the Bluetooth in my car in a couple of hours. I hope it sounds a lot better there than before. Of course, I did the usual and stopped/disabled audiofx and deleted the other three apks, but something still just didn't sound right to me with 2.3.3.0 on the opo or in my vehicle. Didn't see a need to edit the build.prop and I love how it's already set in the sound settings. I've been testing Play with viper and when I go to change the eq, it opens viper right up! Haven't tried poweramp yet, but... definitely, give it a try, if you haven't yet...

Still experiencing the sound buzzing and defects in playback with latest 2.3.4.0 version on lollipop. The problem seems to be fixed when Performance profile is selected (CPU cores doesn't turn off).

If you put in performance profile you might have more battery drain than usual.If u r using boeffela kernal, then in its config app, change hotplug profile to min 2 cores on.

Help needed.

Hi guys. I am on CM12 nightly and flashed the files, absolutely incredible sound on my headphones so thanks a lot. Couple of serious problems though, my mic no longer works (people can't hear anything when I call them) and when I play music on my phone the sound comes out of the earpiece speaker and nothing comes out of the speakers on the bottom of the phone. Restored backup that I took before flashing and no more problems so think I have narrowed it down to this alone.

I guess I could live without it but would rather not as I couldn't believe the difference it made to the audio quality and depth. Anyone know what is causing this problem?

Since I'm not the Dev for this Mod, I wont be able to help you much here.
Try the v4A mod zip present in BlissPop ROM thread and let me knw if it works.

I did exactly that and it didnt work for me. It only seems to work with the built in music player but not poweramp. :confused:

Running BlissPop ROM on a OnePlus One. I guess I'll have to make due without V4A for a while...
