Title:
[Aspire X3400, Nvidia MCP77/78 HDMI, Digital Out, HDMI] Underruns,
dropouts or crackling sound
Status in “alsa-driver” package in Ubuntu:
Confirmed
Bug description:
I have problems with the sound card. Every 29/30 sec a droppout is
heard. This is happening when playing mp3 files but also avi files.
It's quite annoying because i think i have the drivers installed
correctly.
Thanks for any help you might provide.
