I've recently change my PC OS from MS to Ubuntu.



Ubuntu 14.04 can correctly find my HDMI audio but with terrible echo and crackling sound.



I fix the echo issue by following the guide here: Sound problems in Ubuntu 14.04, and Static and crackling in my HDMI audio?. But the crackling sound still exist. I tried updating the video card driver directly from AMD website, didn't help either.



I also try to change the default sampling frequency in /etc/pulse/daemon.conf to 44100 or 48000, both won't work.



I'm using video card MSI ATI R7 260x. How can I fix it, thanks!

Found the solution here:

Cause my PC comes with an Intel Z97/H97 chipset, the solution to solve this problem is:




  1. sudo nano /etc/modprobe.d/alsa-base.conf


  2. Add options snd-hda-intel vid=8086 pid=8ca0 snoop=0 at the end of the file.


  3. Restart PC
