Public bug reported:
I have an acer revo 3700 which uses hdmi output. After some configuring
I got the sound working through the HDMI (following a tutorial from
ubuntuforums.org). This works very well, until I start google chrome.
Then there is no sound in any other application, or through the system
preferences test speakers dialogue. However if I play anything with
sound in my browser (the aforementioned google chrome) then I can hear
the sound just fine.
