Trying to use /dev/dsp0 starts fine for a fraction of a second but then either stays silent or stutters until its audio-queue overflows again. With vdr its similar: when using hw:0 it only stutters (and fills the log with xrun errors). I had a short look once - it uses a very small buffer (iirc about 4kb) and gets constant underruns which it tries to handle via prepare-something but it's unable to recover. With dmix it works fine, probably because of the bigger mixing buffer. > Sure, maybe badly written apps but there must be something wrong if so > many developers have problems with Alsa.
