sidplay does not work when using a recent system without OSS. A patch exists on ubuntu for adding ALSA. See https://bugs.launchpad.net/ubuntu/+source/sidplay/+bug/727573
Build fails with patch applied.
Created attachment 564722 [details, diff] patch to enable ALSA support to sidplay
I have added the patch, I confirm it compiles fine on my system (x86_64-pc-linux-gnu-7.3.0, x86_64-pc-linux-gnu-2.30). Could you paste your build error ?
Can't even autoreconf because of missing macros.
