My sound was working fine until a kernel update. I then went through the Alsa update routine and also the thread listing 10 points on how to check sound. All my codecs are installed as per the checks in that thread.
My problem is that my sound mostly works except for the mail and appointment notifications in Thunderbird and Lightning (using WAV files).
I also notice that when I try play a playlist in SMPlayer it will just strat to skip half way through a song and then suddenly randomly skip a few song and start in the middle of another song. Not sure if it’s related.
