Using USB as audio output?

[Stranyer]

Hi everyone

I know this has been posted in another forums, but without any or good answer.

What i want it's to make an USB to 3.5 Jack adapter to use with my Galaxy S2.

Anyone can help me with this? I'm curretly using RR and as far i could read it says it doesn't have the Dock mode. So, this will be possible?

Thanks for the help!

pinouts

These are the pinouts for the micro USB with instructions on how to make the cable. You can ignore the power input unless you are trying to make a nifty car dock...
Sorry I don't know about dock mode, but different ROMS behave way differently on the USB, so I would try ROMs and kernels until it works. I think ICS is better for USB connecting things.

Good luck.

Tried on RR 2.4 with Samsung Desktop Dock using line out from the dock to speakers - doesn't work.

Was hopeful because I saw Dock audio settings under System Settings --> Dock, but Audio options was greyed out. Likely to be an issue with CM9 and Siyah kernals.

i've gone about it in a different way. i'm fitting a usb port to a blanking cover in my dash board and taking a aux line in from my head unit and power from behind the dash (ignition fed). as i have an s3 i need 1 amp for the power side of things. all parts have come from ebay for about £11.00 about $18.00
