Ubuntu 14.04 Pulseaudio in HDMI sound crackling
Solution 1
Found the solution here:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1321421
Cause my PC comes with an Intel Z97/H97 chipset, the solution to solve this problem is:
sudo nano /etc/modprobe.d/alsa-base.conf
Add
options snd-hda-intel vid=8086 pid=8ca0 snoop=0
at the end of the file.Restart PC
Solution 2
This one helped me: [Static and crackling in my HDMI audio?]: Static and crackling in my HDMI audio?
edit
/etc/pulse/default.pa
look for
load-module module-udev-detect
add tsched=0
load-module module-udev-detect tsched=0
reboot

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!
