Comment 1 pasqual milvaques 2011-08-04 16:29:37 UTC

the same error happens to me with a radeon hd 3430

in /var/log/messages appear this messages when trying to play something:

It seems that pulseaudio is crashed when trayinng to play something and automatically restarts

I have a HD 4350 and i have the same error after the kernel update. 

And videos (only tried youtube (flash and html5)) played too fast.

Comment 3 Xavier Bachelot 2011-08-14 21:07:25 UTC

Actually, not a real bug, HDMI audio is now disabled by default.
Adding radeon.audio=1 to the kernel line in grub.conf will re-enable it.

See https://bugzilla.kernel.org/show_bug.cgi?id=39832 for some more details.

Comment 5 Josh Boyer 2011-10-21 01:08:09 UTC

I'm going to close this one out as this was an intentional upstream change.  As Xavier noted, radeon.audio=1 should get HDMI back.
