Title:
[Dell Precision M3800, Intel Haswell HDMI, Digital Out, HDMI] Sound
has wrong bitrate / pitch
Status in alsa-driver package in Ubuntu:
Expired
Bug description:
HDMI sound output to my U2414H Dell monitor happens at the wrong
bitrate, resulting in sound output at the wrong pitch.
This video demonstrates the problem:
https://www.youtube.com/watch?v=TLCw_-Dr1-8
(Interestingly the rate that youtube plays the video changes as well -
seconds count faster)
If I suspend and resume the computer, then this bug disappears. I
can't find any parameters in /proc/asound that show the incorrect bit
rate. This is a clean install of Ubuntu with 3.13.0-24-generic
will@prefect:~$ cat /proc/asound/cards
