Still affecting me in 12.04 LTS with AMD 64. Kernel = 3.2.0-29-generic
#46. Had absolutely no issues in 10.04 LTS.

All software updated and the additional FGLRX driver added for my  ATI
RS780 HDMI Audio [Radeon HD 3000-3300 Series].

System spews out "cannot set freq 48000 to ep 0x86" No audio. No audio
devices shown in the "Sound" settings.

Tracked it down to the Logitech C310 webcam.

Workarounds:
Sometimes executing "sudo force-reload" once fixes it. Sometimes doing this a 
second time is necessary.
Best solution is to plug in the webcam after I am fulled logged into the 
system. Using this method, everything works like a charm. No spewing of errors 
either.
