Steps to reproduce:

Upgrade from kernel 2.6.27to 2.6.32 and issue command ls -l /dev/snd to see if devices exist

Created attachment 27452 [details]
Fix detection of riptide firmware

Comment 3 Gary James 2010-08-15 19:29:33 UTC

One patch and kernel recompile later.  Result.  Perfect

Thank you very much.  Output of /dev/snd

Thanks for testing.  I applied the patch now to sound git tree with Cc to stable kernel.
