View Full Version : [ubuntu] Suddenly unable to play multimedia files with sound.

August 1st, 2008, 06:45 PM
I'm running Hardy Heron and I have a problem where I'll suddenly be unable to play multimedia files with sound until I reboot the system.

I'm half convinced that certain web pages that play video automatically are locking the sound card or another multimedia device.

Here's my LSPCI:
00:00.0 Host bridge: ALi Corporation M1647 Northbridge [MAGiK 1 / MobileMAGiK 1] (rev b0)

01:00.0 VGA compatible controller: nVidia Corporation NV20 [GeForce3 Ti 200] (rev a3)

Is their a way to forcibly reset the sound card?

If you mean Flash videos, then install the libflashsupport package and you should be fine. But beware, Firefox may crash sometimes when visiting pages that contain Flash after doing this.

I'm having the same problem, but the solution hasn't worked.
Also, is there any way to stop the crashing caused by this plugin?

You should try changing from ALSA to PulseAudio or viceversa. That just works most of the time for me!

The only architecture I can get ANY sound to come up on is OSS, but then it doesn't work in firefox. I'm about ready to throw my computer across the room right now, as I now have two without any sound and different problems. What gets me is that this one worked only yesterday
