I'm new to Linux so please bear with me. I have Lubuntu 13.04 installed with both ALSA and PulseAudio. The problem is that my audio periodically stops completely(especially when playing bandcamp/soundcloud in Firefox) and I have to do alsa force-reload in terminal to get it working again. It's incredibly frustrating. Sometimes it happens once in a while other times it continues cutting off after multiple alsa reloads. Is there any solution to this?
EDIT: Forgot to mention I'm using a USB soundcard as my default.
