hdmi sound output is distorted, reedy
Hi,
ubuntu 14.04
. NVIDIA GeForce GTX 860M
. Intel Core i7-4712MQ
whether with gnome 3.10 or unity, whether on nvidia or haswell graphics (using prime to switch) the problem is the same :
hdmi sound output is distorted, reedy (vlc, rhythmbox, firefox...)
through headphones, sound is ok, through laptop speakers sound is ok
with an older laptop with just an intel chipset for graphics & under 12.04/unity & connected to the same hdmi display & audio device, sound is ok
I've searched the web, i've changed sample rate, tried many settings from pulse audio and gnome alsa mixer - but the mixer seems in trouble to sort things out between the haswell & the nvidia card which could point to an alsa issue ?
thanks for help !

When you use Unity you are using Gnome. Unity does not replace Gnome as it is a shell, not a desktop.
Changing session will not alter the sound. The suond subsystem (Alsa and Pulse) is 100% the same underneath. It's as effective as changing desktop wallpaper and expecting something different to happen.
What is the output of:
wget -O alsa-info.sh http://

If you run:
alsamixer
are all levels cranked and unmuted? use cursors to select and edit channels. Use M to un/mute and ESC to exit.
Also be sure to press F6 to change the device you are editting. Then do the same with the Sound application in Dash.
Have you tried a different HDMI cable and a different port on the screen to remove those as a cause of issue?
Thanks

with my old laptop (same cable, same hdmi port -only one anyway) & ubuntu 12.04 sound was ok (cutting for one second or so from time to time but never distorted)
if i run alsamixer :
if i chose hda intel hdmi, i don't have any level shown, i have s/pdif s/pdif 1 s/pdif 2 all set to 00 & i can't seem to be able to change those values
if i chose hda intel pch, i have all the levels unmuted in white or red area + auto-mute on, dynamic power control off, independent hp off & loopback mixing off (i haven't dare to experiment on those settings)

Did you upgrade online to 14.04 from 12.04 or did you clean install 14.04?

Hello,
I also applied the workaround suggested by "sushi" and "mika" and it's working for me. Thanks a lot.
