Public bug reported:

Occurs consistently in the same locations of audio streams decoded from
FLACs/MP3s through foobar2000. Also, performing unrelated tasks will
sometimes cause similar dropouts (e.g. perhaps simply scrolling up and
down a webpage or changing tabs in Firefox). The audible dropouts last
about a second.

Also occurs in other applications that utilise Wine (e.g. Caesar III).

Has been an issue since I did a clean install of Ubuntu 12.04 from
11.10, and still with 12.10.

Radeon 6870 -> HDMI -> Pioneer VSX-920 AV Receiver (splits out audio to
speakers) -> HDMI -> Samsung LA22A450C1XXY

Thank you
