:Playing sound using pcm(4)/snd(4) gives bad quality: hiss and hops, like sound isn't playing for very short time periods.
:
:This is experienced:
: - not having SMP in kernel config (eg GENERIC)
: - from dfly-1.5 26th December '05 (24th is ok using kernels from chlamydia);
:including HEAD.
:
:dfly-1.4 is ok, including 1.4.4.
:
:Using audio/mpg123 for MP3, 'cp test.raw /dev/dspW' or pcmplay for decoded sound.
:Buffering audio data with mpg123 -b doesn't sound like making any difference.
:
:CPU load doesn't sound like making any difference.
:Problem experienced on several systems, using snd_via8233 and snd_ich.
:
:No X11 used.

    Hmm.  That's quite odd.  There aren't any significant source code changes
    bewteen the 24th and 26th of December (I diff'd the 23rd and 27th to be
    conservative).
