No sound on Debian 9
by lucmove from LinuxQuestions.org on (#5GN8V)
I have had Debian 9 running on my Desktop for years. Sound is configured fine, but I did it a very long time and installed JACK and many other things. Summing up, it's complicated.
Now I have a fresh Debian 9 installed as a virtual machine in VirtualBox. Sound does not work. When I try to play a WAV file in Audacious, it tries, but halts as soon as it begins to play. Under Settings, only ALSA is accepted. Everything else causes error messages.
I also tried playing the WAV file with mpv. Again, it begins to play then halts.
What can I do to have sound using ALSA? I really absolutely prefer ALSA.
TIA
