I am having problems using my audio ports in Ubuntu 14.04. I didnt notice this before, because I use wireless speakers and they use a USB port. But today I tried to use my headphones and I heard horrible static and some kind of lag. I was listening to music on youtube at the time and I also saw that the video/music began to play at a faster rate. This was again confirmed when I listened to music on Rythmbox and the same thing was happening.

Then I tried to listen to music via my monitor that is connected to my computer with a HDMI-cabel. The static was there too, making the music hard to recognize... needless to say, it was unlistenable.. unless you like some really weird and crazy kind of music remixes. ;)

Otherwise the sound works perfectly via USB.

What can I do to fix this?

output of sudo lshw -C multimedia follows

Best regards! :)

I believe this to be a bug in the driver, there appears to be a workaround which may work for you:

You have to modify the following line in /etc/pulse/default.pa

load-module module-udev-detect

with :

load-module module-udev-detect tsched=0

If this approach doesn't work for you, look here and here for further instruction.

I've used a couple of days ago bluetooth headset and had a similar issue. I went to the pavucontrol and in the configuration tab where it was possible to switch to a mode with better quality (but sacrifice the microphone). After that, everything was perfect.
