Can't open audio device /dev/dsp: Device or resource busy. I tried to google and found a solution with running this command: sudo modprobe snd_pcm_oss. yes it works.

https://stackoverflow.com/questions/46208266/how-to-create-sound-devices-for-debian-in-docker
I'm using various docker containers which, under the covers are built on Debian sid.

change default audio device (debian woody)

There's no need to change this, Linux supports audio output both through /dev/audio and /dev/dsp. The only difference between them are the default settings of these devices, which every audio app will change to its needs. It only matters if you cat a file to the device for testing purposes. So if /dev/audio works, /dev/dsp does, too.

3 The default sound system is ALSA and /dev/audio or /dev/dsp ( OSS interfaces, deprecated in Linux) is only an emulation layer over ALSA -- and not even a fully functional one, at that. The default ALSA device is " default ", and if you install mpg123-alsa, it should Do The Right Thing without requiring any options. Share Improve this answer
