Slackware 10.0 sound issues-- CD playing
So, I want to play an audio cd on my slack 10.0 box. First, as suggested in a guide I found somewhere, I ran alsamixer and unmuted/turned up all the channels. "aplay /usr/share/sounds/phone.wav" played a phone noise just fine.
I then realized I had no idea what program could play a cd. I looked around but couldn't find anything, so I started KDE. In there, I used their CD playing app, which started fine, but produced no sound. (as in, the tracks started playing, but with no volume.) If I plugged my headphones into the jack on the cd drive, I got music; if I put them into the soundcard jack which had worked fine for playing sounds on the commandline, nothing.
So, A. how do I play a cd from the command line? Is it possible?
B. Why am I not getting sound from the cd player in KDE?
