Root [SOLVED] M931 audio problem?

Does anybody know why these phones have problems with streaming audio? Is this a hardware or software issue that can be fixed somehow?

I may have mentioned this already.... I can play super HD FLAC audio encoded Matroska videos on this phone without a problem, but can't stream Pandora or YouTube music without the damn audio chopping up/skipping every 20 seconds, even when on WiFi. Music is the only thing I really care about working and its driving me insane!!!!!

-UPDATE-

Finally fixed it. After hours/days of deleting, reinstalling apps, audio engines, wiping cache, wiping Dalvik cache, fixing permissions and countless experiments and reboots, I finally found out what the fu*king problem was: CPU settings. Here's what I did:

I installed No-Frills CPU Control - first one that came to mind, there are a few others on Play Store.
Set minimum CPU frequency to 594 MHz (was @ 384 MHz)
Left maximum CPU frequency @ 1.512 GHz
Set governor to "performance" (was set to "ondemand")
Left I/O scheduler set at "cfq"

Problem solved. That fixed audio my streaming audio distortion problem and I got the added bonus of a substantial increase in performance. youTube, PVStar and Pandora play flawlessly now. This may also fix some other performance issues I've read about in this forum.

**PLEASE** In case some of you are unaware, screwing around with CPU settings can potentially screw your phone up, perhaps even brick it if you're not careful. Do so at your own risk, and have a backup ready in case!!!

Here is a screenie of what I did. Values on left side are what my phone was running at, and you'll see on right side what I requested.

Noobies: Note that I haven't checked 'apply on boot' yet. ALWAYS make sure your phone can handle the new settings! Give your phone a one day stress test with new settings to be sure, then set to boot. Otherwise you may brick your device or get a boot loop! I speak from past experiences with another Huawei :D

I do not have this issue. I stream Pandora, Google music, and others all day long with no skips. You update your prl?

All updated... My phone did this out of the box, actually. Flashing stock76 seemed to fix this, it's just doing it again. I don't wanna wipe it, even though I only keep a small handful if apps. Im lazy, hate having to restore my settings.

I think elk1007 had the same problem...?

stock 76 is my daily driver, probly why I have never noticed it! lol

Increased the minimum CPU freq and changed the governor. I added some info to the first post.

What I'm interested in knowing is, if what values were originally set to are what comes as default? I've never had any outside CPU controller installed on my phone.

Anyway, I'm happy now. Phone is lightning fast now, no choppy scrolling, audio lag, UI lag etc. Of course I lost some battery life but the performance more than makes up for the hit :)

Setting the governor to performance locks your CPU to max GHz and leaves it there. Change min to whatever it males no diff.
Try android tuner to get clear image of your phones behavior. SIO is the best stock io setting
Zipalign and cleanup is NOT v6 only.. All tweakers include that, it happens to be very important, actually that is one reason why opening an installer zip file will break it, it disrupts the zip alignment and screws the file up.
The v6 supercharger scripts will help a lot, you can also use their battery script to recalibrate the readings displayed. Read the text VERY carefully especially regarding 'fix align' setting it for boot does the jobs of two other scripts combined. After running v6 and allowing the radio tweaks run the oak 3g turbo. I had a DL max WiFi of aboutk180kbs after it went to 7mbs and this has been repeated on all the devices I prep for sale... Because it works . my devices run like a bat out of hell (sic) . Get the latest V6 supercharger at xda right now it is the black dog fix. Pull the others as well, also make sure to grab the starter kit.. You don't have to install all the binaries (,zipalign dedupe superuser busybox etc.) Just be certain you have what it needs.

Enjoy. ZepplinRox ! ( he wrote the scripts and guess what CM adopted some of his stuff to include as part of CW Roms. Not bad, huh?)

Have fun!
