[Galaxy S III Accessories] themadproducer:
I have an app called SoundAbout.

When I first tested it 2 weeks ago...it nearly fixed my issue.

More on that in a minute...

With USB DAC, when a call comes in, the MEDIA stream does the skipping until the call is fully ended. Sometimes, media music resumes normally, other times it does the FASTFORWARD 5x speed skip and dance for a few seconds, then music locks back into normal play and stays that way. This means, if I am in the car listening to loud music, a call will turn the audio into obnoxious digital seizure like sound behavior. Also, if I make a call, the same thing.

I used the UAC222 and the Creative SoundBlaster XFI GO!

Oddly enough, after a reboot, it sometimes DOESN'T SKIP AT ALL on first phone call. Totally weird.

Then came SoundAbout app. I am successfully able to route all notifications to the headset when I am using. That works NICE. But that's not the main reason I got it. At one point, I told it to route all MEDIA to digital (it listed HDMI) and if a call came in, the ringer would ring WITHOUT anything skipping. Then when I answered the call, the skipping would start. At least it gave me a window where I could MUTE the car stereo before taking the call. It was a crude workaround.

The by-product is that 50% of the time, after un-Docking my S3, I would totally lose all media sound. I would then go into the SoundAbout app and tell it to not route audio to digital. Then I would need to adjust my S3 media volume, and sound would return to normal.

Then the app received 2 minor updates this last week or so...and now digital media hacks don't work at all. The notifications hack still works.

I am not sure if I want to pursue this crap but it is obvious to me, that someone with programming skills and knowledge of Android audio routing etc., could find a way to fix this crap or a really good workaround. I have still yet to permanently mount my CraigsDock hoping I will find a solution soon but I exhausted my Google search and aside from CZeddie's input...it's a bloody rare topic. Even those that use high end boutique DAC's with their S3's and such, are not breaching the topic of STUTTERING or MEDIA stream vs Phone Call stuttering issues etc.

Finally this summary:

I have 3 ways to get audio to my car stereo and all 3 are not the solution I am looking for.

1) USB analogue...which is initiated when a car dock like CraigsDock or iDock, has a resistor value across pin 4 and 5, and triggers Dock Mode and outputs Analogue audio to USB. PROBLEM...while charging, my i747m will not operate without HORRENDOUS CPU noise and ground like buzz noise especially between tracks or button pushes. I tried all kinds of rewiring tactics since I have Audio wiring skills and electronics background. FAIL

2) USB DAC digital audio, takes care of the noise and buzz issue 100% and sounds great with the purchase of an external DAC...PROBLEM unfortunately skips or stutters during phone calls. FAIL

3) Headphone Out...works without stutter issues and all audio streams pretty much work in harmony.

1st problem....is that Android devs decided to reduce the volume by 25% each time you plug it in. I found a workaround with an app named EarSmart. When I plug in a jack now, EarSmart raises the volume to 100% or any pre set desired volume. That RETARDED warning toast message pops up but at least that's one less step when docking. Other apps I tried did not work.

2nd Problem...notifications not coming through headset jack. Worked around that issue with SoundAbout as mentioned above.

3rd Problem...with my CraigsDock, using the Headphone Jack for audio means I have to add another step when docking. For such a clean and high end dock, this extra cable downgrades the experience. WORSE THAN THAT...I have to create my own COMPLEX cable to make this work...or severely hack into the CraigsDock supplied cable. It cannot be a OTG cable or a DOCKING cable. In other words, the pins need to be un-tampered.

LASTLY...

I have both the CraigsDock and the iDock.

I counted the steps it took for me to securely dock my S3 into the iDock and start listening to music. The CraigsDock, using USB out, potentially saved about 8 minor steps and could be done one handed. Seriously...it sounds like we are being fussy here...but I used ti do this with my HD2 and it's dock. One hand to dock, click on Poweramp, press play. Easy.
