On a Thinkpad T15g, I can get an Aftershockz OpenComm headphones to work over Bluetooth, but not the microphone. With Google Meet, the options don’t show the Aftershockz mic.

This Aftershockz mic show up on Google Meet with Chrome on Windows 10.

It doesn’t show up with:

  • Linux 5.12.9-1
  • Linux 5.10.42-1
  • Linux 5.4.124-1

Here’s the same Google Meet panel with Chrome on Manjaro.

I see that @nikgnomic and @Olli were helpful on " Headphone Mic doesn’t get detected in February , but I’m not sure if I have the same issue.

Additional guidance or diagnostics would be welcomed. Thanks.

Trying to follow through on …

  • Bug 207131 - No headset capture on Realtek ALC233

I ran the ALSA Information Script, and posted it at:

Am I supposed to be interested in Node 0x12 ?

@nikgnomic said …

The headset microphone connection is not configured correctly and is shown in ALSA data as a Speaker Output
Node 0x19
and dmesg data does not show a speaker output for 0x19

… so here’s the dmesg:

Trying …

sudo hdajackretask

… gives me …

20210712_Hdajackretask
20210712_Hdajackretask560×722 35.2 KB

I then tried on Pin ID 0x19

(check) Override
Microphone
Apply now
Reboot

After reboot, I started up Google Meet again. The Aftershockz mic still is not an option.

If I again check:

$ sudo hdajackretask

… the Override is enabled for Pin ID 0x19.

The Bluetooth mic is now working … in a strange way. It seems to need to be woken up!

If I start Skype … Tools … Audio & Video Settings … , the dropdown menu includes:

  • Monitor of OpenComm by AfterShokz

20210713_Skype_Settings

In Skype, if I

  • Make a free test call

… then … we can see in the KDE Audio Volume settings,

  • Bluetooth Input (OpenComm by Aftershokz)

20210713_KDE_Audio

This is strange. It’s a workaround, to start up Skype, so that I can use Google Meet!

Searching on “alsa ALC285”, I found on lore.kernel.org

I wonder if that’s a fix that will eventually solve this issue.

Additional suggestions are welcomed.

Does going to pipewire help?

Sorry, I’m not familiar with Pipewire. What do you suggest that I do?
