My monitor is not a BENQ, it is a Samsung SyncMaster T260, but my bug report
#33438 was marked as a duplicate of this one.

However, I can confirm that using radeon.audio=1 with kernel 3.2.2 (arch linux)
is now working fine.

I don't know which kernel version fixed it though since I've been using
radeon.audio=0 since about a year ago.
