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:

(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
0 [HDMI ]: HDA-Intel - HDA Intel HDMI
1 [PCH ]: HDA-Intel - HDA Intel PCH
2 [U0x46d0x809 ]: USB-Audio - USB Device 0x46d:0x809
