LXC container and USB audio dongle
by mackowiakp from LinuxQuestions.org on (#58DQ8)
I have an LXC container configured, which contains a Debian Buster 18. The container runs on a QNAP NAS (Intel 64 bit 8 GB RAM). The QNAP firmware is of course based on Linux.
I plugged a USB audio dongle to the USB port, which I would like to be a sound card for Debian installed in a container.
Unfortunately, neither ALSA nor PulseAudio can see this card, although the USB subsystem recognizes the dongle correctly. Below appropriate outputs. They are identical both when run from the NAS itself and from a container.

PulseAudio Sound ServerWhat can I do to make USB audio dongle available for Debian in container?
