Audio stuttering on media playback with sndiod

[Daniel Bolgheroni-6]

Hi,

audio is stuttering on media playback when run through sndiod. It's OK
without it.

Here is an example of audio/cmus attaching to play a mp3 file:

x250$ doas sndiod -ddd

(... flood)

The same on a X220 gives me this (it's OK here):

x220$ doas sndiod -ddd
snd0 pst=cfg.default: rec=0:1 play=0:1 vol=23170 dup

cmus0 vol=127,pst=run,mmc=off: set weight: 23170/23170

I couldn't spot any difference in the initialization, but on the run,
the former case is flooded with this pair of messages:

snd0: rec hw xrun, rused = 2880/7680
snd0: play hw xrun, pused = 4800/7680

From source:

#define XRUN_ERROR  2   /* xruns are errors, eof/hup buffer */

OK, but I can't figure it out why this is happening on one box and not on the
other. dmesg's for both boxes below.

Thank you.

Thanks. Few notes for the mailing-list archives:

Certains laptops have a "disable microphone" knob in the BIOS which
makes the device operate play-only, but it still reports full-duplex
capability. This confuses any full-duplex program, including sndiod,
and makes sound stutter. I've found no way to detect this situation.

Until we manage to properly detect it in the azalia driver, I'd
suggest not using the BIOS knob (ie keep your microphone enabled). To
disable it, run as root:

        chmod 600 /dev/audio[0-9]

and restart audio programs (or reboot if unsure). This is reliable
because sndiod has no root privileges; even if it is compromised, the
attacker won't be able to record. And this works for everyone, even
for those without the BIOS "feature" :-)
