Description bgraceysee 2020-01-16 09:58:33 UTC
Hi all,

I have an external usb heaphone and microphone (HyperX Cloud)

I guess its equally likely there are issues in the external device; however it was working on previous versions of Ubuntu; after upgrading from Ubuntu 16 to 18 - the usb microphone input is still detected; but never shows receiving any sound.

Export of logs: cat /var/log/syslog* | grep -i pulse

Please give alsa-info.sh output.  Run the script with --no-upload option and attach to Bugzilla (don't paste to the form).

Thanks.  Also could you give lsusb -v output (for this device), too?

Thanks.

A test fix patch is below.  Please give it a try.  It'll skip the invalid mixer element.

Comment 7 bgraceysee 2020-01-16 12:03:44 UTC
Thank you for the _insanely_ fast turn around on this!

Are there any links on how to test the fix patch? I do have some technical abilities; but no experience in applying driver patches.

I did look around and found
https://alsa-project.org/wiki/System_Maintainers_documentation - but the `alsa-driver/INSTALL` link isn't active

Also found this - which makes me feel testing a patch is somewhat involved; https://carlowood.github.io/alsa/index.html (Understand this is a completely different patch; just googling "how to apply Patch for ALSA")

Again; blown-away by turn around on this - thanks!
Comment 8 Takashi Iwai 2020-01-16 13:18:12 UTC
Not really, the instruction there is way too old.  Basically you need to rebuild the kernel after patching.

At best ask you distribution how to build a kernel, or let them building a test kernel with the patch.
Comment 9 bgraceysee 2020-01-16 13:33:07 UTC
Ah right; gotcha

So the fix goes here(ish) https://github.com/torvalds/linux/blob/04cbfba6208592999d7bfe6609ec01dc3fde73f5/sound/usb/mixer.c#L1664

Thanks again; I'll see if I can get any suggestions from Ubuntu

Brent

FYI, the patch went into sound git tree, commit e9a0ef0b5ddcbc0d56c65aefc0f18d16e6f71207.
But it's for 5.7 kernel.
