[Virtual-pkg-base-maintainers] Bug#697047: base: no sound with hdmi video card SAPPHIRE RADEON HD6450 with radeon driver, ok with fglrx driver

[mirko]

Package: base
Severity: normal

Dear Maintainer,
my computer is a HP microserver and hasn't a sound car.
My graphic card is a Sapphire Radeon HD6450 with a HDMI output.
My monitor Eizo Fs233 has a HDMI input and I want to use the HDMI output of the video card for sound.
With the default radeon driver I don't have no sound. In the sound settings I try "Test speakers" and it says it is everything good, but I can't hear any sound.
If I remove the radeon driver and install the ati proprietary driver (fglrx driver) I can hear sound. But with the fglrx driver after two or three days I get a blank screen and I must reinstall the system.
Can you fix the problem with the radeon driver?
This is my video card:
01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Caicos [Radeon HD 6450]
01:00.1 Audio device: Advanced Micro Devices [AMD] nee ATI Caicos HDMI Audio [Radeon HD 6400 Series]
