Shure MV7 USB Microphone seems to work with Thinkpad but not XPS

I have two Linux laptops. Both are running Kubuntu 20.04.2 and are using a 5.10 kernel. One laptop is a Lenovo Thinkpad T14s AMD, and the other is a Dell XPS 13. Both have pulseaudio 13.99.1 installed.

I also have a Shure MV7 USB microphone and two different docks; one is USB-C, the other is a TB3 dock that falls back to USB-C (the T14s AMD doesn't support TB3, the XPS does).

Using either dock, the Thinkpad is able to work with the microphone. Using either dock, the XPS 13 is unable to work with the microphone. A MacBook Pro having TB3 does work with the microphone using either dock.

Here is the dmesg output from the working Thinkpad:

Here is the lsusb output from the non-working XPS:

Bus 005 Device 014: ID 14ed:1012 Shure Inc.

Any ideas on how I can get the microphone working with the XPS 13? Plugging it in using a basic USB-A to USBC adapter also does not work.

Note that the XPS draws 45W of power, while the Thinkpad draws 65W, so I don't believe the issue is that the dock cannot power both the XPS and the mic simultaneously.

Update 2021-02-27:

I updated the kernel on the XPS to 5.11 but that didn't help.

Here's a bunch of output from various commands. For most of them I removed entries that weren't related to the MV7.

I then installed the libsox-fmt-alsa package on the XPS, but that didn't help.

grep intel /etc/modprobe.d/alsa-base.conf

Working Thinkpad:

options snd-intel8x0m index=-2

Non-working XPS:

options snd-intel8x0m index=-2

I also ran the command dpkg -L linux-modules-<version>-generic | grep snd on the two machines, output to a file, scrubbed the kernel version, and diffed the output. The only differences are that the XPS has more kernel modules loaded than the Thinkpad. Here's the cleaned-up diff:

> /lib/modules/.../kernel/sound/soc/adi/snd-soc-adi-axi-i2s.ko
> /lib/modules/.../kernel/sound/soc/adi/snd-soc-adi-axi-spdif.ko

I then went through and ran sudo modprobe -r snd-* for each of the listed modules and replugged the microphone. The dmesg failures still stream through in the same way.

This output then repeats in a loop, much like with the dmesg output.

You may try a solution method similar to what was used in this question Only "Dummy output" (sound) in Ubuntu 20.04 after reboot - Broken driver / moduleThere, the problem was with sound output. This is related but not the same.

Try using a comparison between systems that work and do not work (as you already started to do). Check a few informational commands. I am copying here what was used in that other case. Some of the tests pertain to both cases. Minor variations should also help.

$ cat /proc/asound/cards
$ lsmod | grep snd
$ dpkg -L linux-modules-<your version>-generic | grep snd
$ inxi -SA
$ lspci -nnk | grep -A 1 Audio
$ uname -a
$ lshw -C multimedia
$ dpkg -l | grep alsa
$ grep intel /etc/modprobe.d/alsa-base.conf

Please post the output, and also take some time to pinpoint (what you judge as) meaningful differences and indicate them, so others can help you better.

You may be missing a package, driver, etc. If you are lucky, it is only a linux-modules-... package.

First, the MV7 worked fine on my desktop pc using Ubuntu (18.04).

After I re-plugged some USB devices, I had similar issues: connecting/disconnecting loop with the message:

1:1: usb_set_interface failed (-71)

Although the (USB) webcam and video streams were stuttering. I reverted the replugging and everything was fine again: The "fix" for me is, using a USB2 and NOT a USB3 slot for the MV7.

Looks like the USB3 issue is not only related to the MV7: .

I have Ubuntu 20.04 on a Dell XPS 15 9550 and was facing the same issue where the mic would reboot infinitely.

Based on on this answer, it seems the problem is PulseAudio communicating with the mic in a way that makes the mic's firmware crash.

I replaced PulseAudio with PipeWire and now the MV7 works perfectly. I used the following PPA:

Be sure to follow the instructions about disabling the PulseAudio service and give the system a reboot after the fact.
