0AD and OSS

[sarcoma]

Why is 0ad using old OSS and monopolizing the card?

sudo fuser -fv /dev/snd/* /dev/dsp*
                     USER        PID ACCESS COMMAND
                               10571 F.... pyrogenesis
/dev/snd/pcmC0D0p:             10571 F...m pyrogenesis
/dev/snd/timer:                10571 f.... pyrogenesis

Other OSS program:

FATAL: cannot open dsp device /dev/dsp
/dev/dsp: Device or resource busy

0ad uses OpenAL for sound. And afaik 0ad doesn't need to monopolise any sound card. But OpenAL might do some stuff. Could you run 0ad with `--nosound` flag?

Thank you, Vladislav.  With --nosound, 0ad doesn't access the card

                     USER        PID ACCESS COMMAND
/dev/snd/controlC0:  root        441 f.... alsactl

and OSS program runs with this module loaded snd-pcm-oss.

Seems like an ALSA thing though, pretty much any program that needs audio blocks /dev/dsp.

I found out ALSA comes with aoss to run old programs.

Thank you.
