Audio expansion card not working (worked before)

Which Linux distro are you using?
Which release version?

Debian Sid, updated about a week ago.

Which kernel are you using?

6.11.4

Which BIOS version are you using?

3.03

Which Framework Laptop 16 model are you using? (AMD Ryzen™ 7040 Series)

AMD Ryzen 7 7840HS w/ Radeon 780M Graphics

I have had this laptop for about a month. When I first got it, I tested the audio expansion card. My notes were that this showed up under ALSA as card #2 and I didn’t have any issues. I hadn’t used the audio card since then, until I tried to now, and I can’t make it work.

To be clear, I am referring to:

I don’t have the device listed:

$ aplay -l
**** List of PLAYBACK Hardware Devices ****

I had thought the audio card was a USB device. I don’t see it in lsusb, though.

Things I have tried are:

  1. Reverting to the Linux 6.10 kernel that I think was running when I initially tested the audio card.
  2. Unplugging and re-plugging the card; nothing shows up in dmesg for the disconnect or the connect.
  3. Plugging the module into a different known-working slot (still nothing in dmesg). Likewise, using my Ethernet module to ensure that my usual audio module slot is working fine.
  4. Booting a Debian stable live USB stick, checking lsusb and dmesg and unplugging/plugging the module.
  5. Plugging in a separate, brand-new audio module; same results.
  6. modprobe snd_usb_audio (module loads, but doesn’t do anything).

At this point given that a brand new card does not work either, I’m pretty sure I have a software/configuration issue, but I don’t know what is wrong.

Can somebody with an audio expansion card and Linux please help me with:

  1. Does the device show up in lsusb? If so, please paste the entry.
  2. What driver is responsible for handling the audio device? sudo dmesg | grep snd should show it, I think.

Any other advice would be welcome.

Thank you,
Corey

Do you mean something like usbreset? I don’t think that can help me here, since the device is never even detected, but I’m not sure what you mean.

Physically unplugging and re-plugging the card should reset it as well, I would think, but I see no messages from the kernel when I do that.

I also tried a power cycle of the laptop, with 30 seconds in between power off and power on.

I tried Ununtu 24.04.1 LTS live from a USB stick. That did not work either, as far as I could tell.

  • no listing in aplay -l
  • no apparent listing in lsusb
  • no messages from the kernel when unplugging and re-plugging the card

Ok, I figured it out. The USB device doesn’t appear until headphones (or some such) are plugged in. Then:

The device shows up in lsusb as:

Bus 001 Device 010: ID 32ac:0010 Framework Audio Expansion Card

When headphones are unplugged, the device disappears.

Nov 02 19:38:21 lizard kernel: usb 1-2.3: USB disconnect, device number 10
Nov 02 19:38:21 lizard acpid[1424]: input device has been disconnected, fd 20

Wow, that behavior is counterintuitive. There should be no problem now that I understand, but this should really be documented in a manual somewhere.

I have a USB C to 3.5mm by ugreen that does this

I think Framework’s card readers do the same.

I think they do it for power saving reasons

I am experiencing what appears to be the same problem. On plugging in headplones, the kernel reports:

I think what @sinatosk says makes sense: that it’s probably to save power.

For all I know, that’s expected behavior for USB audio devices in general, but first-time users of such things (like myself) can get tripped up. This could easily be cleared up by documentation, but the audio expansion card doesn’t have any that I can find. That’s my only gripe.
