Hi Leif, I did review some of the archived messages from 2021.
For USB audio, I don't think there has been much progress. Since 2021, there has been more support for virtio in qemu. I believe in qemu 8.2.0 ( https://www.qemu.org/2023/12/20/qemu-8-2-0/ ) (back in 2023) device emulation was officially supported. I have no experience using the virtio-sound system, but is should be in a more usable state worth testing. Emulation of HD audio controllers and codecs can also be done in qemu, but I have been warned about some potential quirks and bugs that exist. In my own personal testing (probably about a year ago), I believe if I remember correctly, I worked by passing a host system HD audio device to the qemu emulator + a small amount of baremetal testing. I was able to produce a sine wave using the immediate command input and output registers, but that approach is not very practical. Thanks, Archer Pergande -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
