shell-fm keeps giving ALSA: underrun, at least 0ms and losing sound while it shows the error, it is a rather intermittent error. Sometimes I can run it for hours with no issues other times it starts right after I start shell-fm. I do not use pulse audio or artsd, only alsa.

So no one knows what this is or how to fix it? I have googled and checked the Debian BTS all without luck. I remember something about creating a asoundrc but haven't been able to find what to put in it to fix this issue.

shell-fm keeps giving ALSA: underrun, at least 0ms while running it in lxterminal.I use alsa with lxde, not pulseaudio or artsd. When I close it with ctrl+q it gives the following output.My ram is fine, ran memtest several times this week to check so I am pretty sure that isn't the problem. Also I am not having any issues with other sound apps like mplayer, moc or with videos in smplayer.

ALSA: underrun, at least 0ms.
