Realtek ALC4080 USB audio device support

[Dave G]

Audio does not work on the MSI Z690 TOMAHAWK WIFI DDR4 (MS-7D32) motherboard when using Kubuntu 22.10 due to Realtek ALC4080 USB audio device issues. Earlier ALC4080 problems were resolved against Gnome but under Plasma desktop it's still broken due to a pipewire problem.

This patch https://gitlab.freedesktop.org/pipewire/pipewire/-/merge_requests/1429 resolves the issue and has been merged to pipewire master. Please patch kinetic so MSI Z690 Plasma users don't have to wait another 6 months for this to be resolved in kinetic-updates.

wrong package

I'm not sure when or if Ubuntu 22.10 will get any pipewire updates but regarding:

> Please patch kinetic so MSI Z690 Plasma users don't have to
> wait another 6 months for this to be resolved in kinetic-updates.

you should note that Ubuntu 22.10 reaches end of life in 6 months (https://wiki.ubuntu.com/Releases).

The fix for this bug however is already in Ubuntu 23.04 which is due for release in April 2023. It might be possible to install the fixed version from 23.04 into 22.10, or that might create new problems. I haven't tried...

Thanks for the note. I was unaware of this April Ubuntu 23.04 update. Cheers.
