Yeah, I installed the SDL mixer, Timidity, and fixed the ini file.
I'm pretty sure I'm using ALSA, since I don't remember changing it, and using alsamixer effects my sound. The volume is at max and so is the PCM section, and I made sure to mute and then unmute both of them.
For some reason, after I installed the SDL mixer and Timidity, the DoomRL I currently had would not start up - it would just flash for a second, then throw me back to the terminal, or if I ran it outside of a terminal then it would just close immediately. Redownloading and running from that seems to work, but still sans sounds/music despite checking the volume.
