Volume control and muting not working with X1 Yoga / FC33
HW: Lenovo X1 Yoga 4 (aka X1 Carbon 7)
Installed Pipewire 0.3.11 from FC33 repository and enabled PA replacement as per the recent blog. Works great with PA applications however my keyboard volume and mute buttons (scripted to change the default sink volume) no longer work. pavucontrol sliders work fine but there does not seem to be a passthrough to the HW ALSA volume control in alsamixer.
Also the HDMI/DP sound output is selected by default even when it is unplugged, requiring manual selection of the speaker output in pavucontrol.
(Also not recent 5.9 kernel change for the DAC routing to properly support the front and rear speakers. - https://email@example.com/T/#mc511358daf828088e541e25b3b239dbdef84c386)
