[Aspire X3400, Nvidia MCP77/78 HDMI, Digital Out, HDMI] Underruns, dropouts or crackling sound

[lukamatey]

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.

same problem, same machine but have run 14.04 since it came out and have updated 2 times per week

i tried using proprietory nvdia drivers, just ripped my screen, now using gallium 0.4 and putting up with the sound annoyance
