I have used DWM before on a laptop - it was nice and minimal… perfect for that old laptop. I just got myself a refurbished i5-based desktop PC and I decided to install Slackware and use DWM on it. For networking, I have network-manager icon running in system tray (using systray patch). For volume control, I have a simple script (wrapper for amixer) to help me with that. But, I also need to test some headphones for my kids. So, I just found out that ALSA actually have a binary speaker-test to help with that!
A simple test on simple stereo speaker (2-channel) can be done by running:
$ speaker-test -c 2 -t wav -l 4
That is all I have to say about that.
