Hello. I'm running StepMania 3.9 on Gentoo Linux, and I'd like sound output to go to /dev/dsp1, not /dev/dsp.
I've edited Data/StepMania.ini to change SoundDevice to /dev/dsp1, but this only seems to take effect in the ALSA initialization, not OSS (the ALSA loader tries and fails to open /dev/dsp1, then OSS tries and fails to open /dev/dsp).
When I specify both /dev/dsp1 for SoundDevice and OSS for SoundDrivers, I see that only OSS is tried, but the device is still /dev/dsp (which is in use by other applications).
I've also tried using aoss, but it seems to ignore the ALSA_OSS_PCM_DEVICE environment variable that its man page says it should honor.
Is there another way to specify an OSS PCM device that should be used?
