I've been using my current Ubuntu installation for several months. However yesterday I noticed that the audio was not working properly. Whenever I play a video on Youtube, the sound keeps breaking off intermittently. Sometimes is plays out of sync with the video and sometimes at twice the normal speed.
At first I thought it was a browser problem but I noticed the same symptoms when playing a file in VLC Media Player.
This is the result of
sudo aplay -l:
** List of PLAYBACK Hardware Devices **
card 0: Intel [HDA Intel], device 0: ALC268 Analog [ALC268 Analog] Subdevices: 1/1 Subdevice #0: subdevice #0
I've checked all the drivers and packages and they're all fine and restarted more than a 100 times (literally!).
What could be the problem?
