USB Audio device: Shure MV7 not recognized #98
Comments

I got that same issue. You can select your Shure MV7 in the Ubuntu Sound settings. That's why I think it is a pulseaudio related issue. |
I managed to get the microphone portion of this working by adding https://gist.github.com/vchuravy/a25ea9533099224a0c4604191f6c668d in /usr/share/alsa-card-profile/mixer/profile-sets/ (Archlinux) and adding:
It seems like the device freezes when being probed for Audio out. |
I would report this at https://bugzilla.kernel.org . Also, if you can, try the latest kernel where the support for USB implicit feedback devices is better supported. @tiwai - FYI. |
can confirm this is big problem, got MV7 especially for videos on linux... sadness, using Fedora 33, same stuff hapenning, mic is just in restart loop, @vchuravy solution didn't work either |
@mc0de I've made a very tiny bit of progress. First, I had to remove an entry in I can't say for sure, but it seems like the zoom program might be making matters worse, as the microphone seems more likely to come up with the correct sample rate when zoom isn't running. I wish I knew where and how I could direct my efforts to get to the bottom of this. Between alsa and pulseaudio I'm not really sure what tools I need to learn to use to even capture error telemetry. |
There are some improvements in the USB kernel driver which may fix this issue. You may try 5.11 vanilla kernels for Fedora (https://fedoraproject.org/wiki/Kernel_Vanilla_Repositories) or compile the latest upstream kernel yourself. |
Thanks for the tip. I tried 5.11.0-rc6, and unfortunately the behavior remains the same.

For what it's worth, I have two Linux laptops, one works pretty well with the MV7 and the other does not. Here's some output from |
Yesterday, I looked with @mc0de into why his Shure MV7 doesn't seem to For one, the microphone sometimes goes into a seemingly infinite
But sometimes, it only disconnects and reconnects a few times before When the microphone does eventually stabilize, changing the device The microphone seems to draw about 75 mA from the USB port when If you unload the We only had an hour or two to look at this, but my wild a** guess would We tried adding extra hubs between the USB root hub and the microphone, |
I did get the shure mv7 recognizable using vchuravy conf and his tweaks but it does not record any sound for me in ubuntu. I'm not that knowledge in linux but if there is anything I can do to test stuff feel free to ask me. |
My "fix" was using an USB 2.x port (I had the reconnecting loop on USB 3.x ports): |
This week I tested the MV7 over a USB2 port. Wasn't easy since my laptop only has USB3 ports, so I had to dig up a USB dock that happened to have one USB2 connection on it. Happy to say it appears to work flawlessly. Thanks @S-o-m-e-0-n-e ! |
@ntl you're welcome |
oh it's work. 1 of 6 usb ports approached. I used Windows 6 months. today i can remove windows!!!!! |
This not worked for me. But I managed it to work using @vchuravy method + some manual steps:
This should be done on every boot. |
Use Ubuntu 21.04 and pasted @vchuravy config file in After reboot system with unpluged device, and plug it back. |
Hello! i hope this is the right venue for reporting not working audio devices.

https://gist.github.com/vchuravy/f5f8ee972d5e2179387c8c53423379f6During the pulseaudio session I plugged the device in and then unplugged it. I am happy to dig in, but I would need some guidance on where to start. As a side-note the microphone seems to work on Android so I am wondering if they are using a different driver.
The device has a head-phone jack with feedback from the mic, and without pulseaudio running I hear the microphone inputs.
So I was wondering if this was in particular a pulseaudio issue.
