I hope this is on topic here.

I seem not to be able to run sidplay2 on Linux with ALSA. It uses OSS,
and so I cannot play sids and have other sounds. I couldn't find an
option to tell sidplay2 to use ALSA. I use an Ubuntu package. I saw you
might be able to compile it yourself with ALSA, but I want to avoid this.

What I'm doing is to append "aoss" on the command line, so it would play.
