To get sound when using the OSS API, you have to install "alsa-plugins", and have a file named "asound.conf" in your /etc directory with the following code.

pcm.oss {
type oss
device /dev/dsp
}

pcm.!default {
type oss
device /dev/dsp
}

ctl.oss {
type oss
device /dev/mixer
}

ctl.!default {
type oss
device /dev/mixer
}

Could you please just add native OSS support, so OSS users don't have to have any ALSA packages installed and rely on ALSA emulation? I tried starting Steam with the SDL_AUDIODRIVER="dsp" command, but it still didn't produce any sound. I had to install alsa-plugins to get sound.

My specs are in my Steam profile, which is linked in my github page.
