What is the device (/dev/?) to output audio?
https://www.linuxquestions.org/questions/linux-newbie-8/what-is-the-device-dev-to-output-audio-903047/
A program I have that generates audio uses /dev/dsp to output. In the output jack (machine rear panel) however I do not get anything. But the program gives me the choice to select another device. What device should I select to have audio through it? Also, /dev/dsp is linked to /dev/sound/dsp: Thanks.
