This occured after about 2 minutes of uptime when I ran realtime-amp to
attempt playing an mp3.
Strangely enough, this could only be repeated twice. I've now been playing
mp3s using realtime-amp for a while.
On the subject of amp, DMA timeout errors seem to be a real problem in
2.1.x (though they did exist in 2.0.3x).
For example, using realtime-amp playing through a list of mp3s, say
"amp-rt /usr/mp3/*", every so often one will stop playing, or not even
start and:
Sound output: timeout
Warning: Problems with direct-to-DMA audio
appears.
Does anyone else see this? I get similar problems with MTV (mpeg player
for X).
