We played a mp3 song using mpg123. when the song was being played, we opened about 20 to 25 konsole windows and netscape navigators, ALSA stopped playing the song. After all windows were opened by linux, we checked the dmesg and found that pcm_lib.c debug msg ---- DMA or IRQ problem? ---- being repeated. cat /proc/interrupts repeatedly used shows that the number of ICH interrupts does not increase at all. Meaning ICH interrupts are no longer being received at all. Why does this happen? Is it a bug in ALSA? --Shaju Abraham ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf
