Finding source of audio
I was quietly working on my computer when suddenly audio started playing. I hear Three Stooges, an ad for some movie, some sort of drama tv show, etc. Two possibly three streams of audio playing at the same time.
The odd thing is, i'm not running any media players or have any web pages playing audio or video. I do have several firefox and konqueror browsers up with multiple tabs. Checked them all, didn't see the cause.
Is there a tool that can query alsa and report where the audio is coming from - which apps are supplying it? If it is firefox, is there a plugin or command line tool to report streaming activity for every tab of every browser window that's up?
I'm running Arch linux 64-bit using alsa.
