USB Audio Class 2.0 Framework Release Date

Bump. Surely someone must know? :)

I came here to ask the same question.

I would also be interested to know.

Thank you for your interest in our products. Please contact your local field sales representative for details.

With all due respect, there's at least a handful of folks interested in this answer. The answer you provided is pretty frustrating, as there's no doubt the FSR will need to go ask the TI mothership. Can't you do the same and answer the question here?

Sorry about the confusion. The reason to involve FSR is for the feedback be coming from the customers via the field which in turn drives the development priority.

Regards.

Hi all,

We have developed a (highly) patched version of the audio framework software for the ezdsp5535 board.

It enumerates as a USB Audio Class 2.0 stereo playback (only) device:

1.  Runs under Linux ONLY at present.  Future versions will run under Mac OSX.  Windows version with ASIO driver will also be available in future.

2.  UAC2 async out with explicit rate feedback (ie bit perfect).  Host sends 32 bits data in S32_LE format (but only 24 significant bits transferred to AIC codec in the ezdsp5535 board). 

3.  Supports 44.1/48/88.2/96khz with automatic switching in run-time with supported host software (eg mpd and pulseaudio).

You can download a bootimg.bin from the audio-widget Google group for testing.

The source code is open source and is available for viewing at github.

git://github.com/alexlee188/C5535.git

4.  This is experimental software and is under active development.  We are currently not able to offer any hand holding for setting up the development environment/software libs etc. nor in entertaining feature requests.  This is because we are busy adding new features ourselves to extend the software to eventually support external DAC's through the expansion edge connector of the board for 32/384khz and for 5.1 and 7.1 playback.

Hi,

Is there anything new regarding this? I see this post one year old saying that there is experimental version of framwork suppporting Audio class 2.0. I suppose after one year this should be avialble now.

However looking here:

http://processors.wiki.ti.com/index.php/C5000_Connected_Audio_Framework

this is still supporting only USB Full speed,

please let us know update,

Marek

Hi Marek,

The development for Audio Class 2.0 has been discontinued a while ago and only Audio Class 1 is available in production form.  The Audio Class 2.0 did not move out of the experimental version.

Please let me know if I can help further.

Thanks,

Jarek,

The host drive for USB Audio Class 2.0 was not developed or distributed by TI.  I recommend contacting Thesycon for USB Audio Class 2.0 host drivers.

Thanks,
