lsusb shows the DAC
the kernel drivers show loaded
I just cannot get applications, amixer, alsamixer, rhythm box, to see the DAC.
Anyone have any ideas?
Thanks
Phil
I have two questions to start with:
- What is the output of
alsactl info? - What is the output of
inxi -SMAz?

alsactl init won't help anyway, it doesn't list (for example) the USB headset that I'm currently using. You could try arecord --list-devices.
Those drivers look a little bit old, given that alsa-utils doesn't support the 'info' command, and you're sitting on pipewire version 0.3.48 which is from about 3 years back; and a lot has changed over that time.
Two more things that might help me figure out what I'm looking at:
- What does
pactl infotell us? wpctl status | grep Devices -A5should show what devices are known to wireplumber (i.e. pipewire).

sorting through things.
I found these two lines in dmesg
[ 12.936853] snd-usb-audio 1-1.3:1.0: cannot find the slot for index 0 (range 0-0), error: -16
[ 12.936904] usb 1-1.3: cannot create card instance 0
[ 12.936919] snd-usb-audio: probe of 1-1.3:1.0 failed with error -16
Don't know exactly what this means (yet) but looks suspiciously like the issue....

found some references to a similar error. tried a workaround but it still fails to initialize.

Looks like, perhaps, an incorrect setting for modprobe?
The output of grep -r 'index=' /etc/modprobe.d might help; here's what it looks like on my UM24.04 machine (defaults):
/etc/modprobe.d/alsa-base.conf:options bt87x index=-2
/etc/modprobe.d/alsa-base.conf:options cx88_alsa index=-2
/etc/modprobe.d/alsa-base.conf:options saa7134-alsa index=-2
/etc/modprobe.d/alsa-base.conf:options snd-atiixp-modem index=-2
/etc/modprobe.d/alsa-base.conf:options snd-intel8x0m index=-2
/etc/modprobe.d/alsa-base.conf:options snd-via82xx-modem index=-2
/etc/modprobe.d/alsa-base.conf:options snd-usb-audio index=-2

Oh, also grep -r 'index=' /lib/modprobe.d might be useful.

By the way; this is telling us that the snd-usb-audio driver is not being loaded; which means something is failing on the kernel level (i.e. potentially incorrect settings).
As an example of what we want to see; here's the output given a USB headset connected to my system:
Device-5: Razer USA Barracuda X driver: hid-generic,snd-usb-audio,usbhid
type: USB

Did you find a solution @pjkemp ?
