[SOLVED] Razer USB sound card doesn't work

Message

Hello everyone!

I've got a Razer BlackShark v2 headset with USB sound card dongle and I'm trying to get it work. pavucontrol doesn't show up any external sound devices, only built in and graphics card outputs.

I have the generic ALSA USB/MIDI option enabled in kernel, the card also listed in both lsusb and dmesg with no errors, but it still doesn't work and I'm unable to choose it in pavucontrol. Could you give me an idea, please?

thanks in advance

g-virus,

Code: Select all

lsusb

will give its Vendor and Device ID that will help.

Code: Select all

lsusd -vvv

ill tell us a lot more. So much more that its unlikely to fit in a post.
However, knowing the device class and having information about your entire USB device tree may well be useful.

We may want to see the kernel config. too.
That's another pastebin.

Are they are hints in dmesg?
Who is missing but should be present is as important as what is actually there so please don't filter it.
So, three pastebins please.

g-virus,

in your lsusb you see hardware ID of your razer soundcard. If you google "linux 1532:0529" you will get:
https://linux-hardware.org/?id=usb:1532-0529

Here you will see all needed kernel modules. Two of them you have already enabled:

Code: Select all

CONFIG_SND_USB=y
CONFIG_SND_USB_AUDIO=y

Other are missing. Now if you search with / in "make menuconfig" you will find them.

Hint: To get your needed "CONFIG_USB_AUDIO" you have to enable BEFORE other option:

Code: Select all

# CONFIG_USB_GADGET is not set

then you can enable "CONFIG_USB_AUDIO".

Code: Select all

Device Drivers  --->
    [*] USB support  --->
        [*]   USB Gadget Support  --->
            USB Gadget precomposed configurations  --->
                [*] Audio Gadget

pietinger, thank you! It's true that I actually forgot to enable USB_GADGET option. But I have to say that the problem was actually in kernel that I forgot to install after I have built it. It works well without USB_GADGET in kernel 5.15.59. Sorry guys, I wasted your time

However, I followed the link you have provided and I didn't find those "missing" options. According to this website, for that hardware only both CONFIG_SND and CONFIG_SND_USB_AUDIO are required for kernel > 2.6.35. How did you see the other options, USB_GADGET for example? In the kernel that I have the option USB_AUDIO is available without gadget enabled

'Ordinary' USB audio and audio gadget are mostly different things-- one is CONFIG_SND_USB_AUDIO and one is CONFIG_USB_AUDIO. The first is under Device Drivers -> Sound card support -> Advanced Linux Sound Architecture -> USB sound devices ...which you can guess by how lots of things in ALSA have SND in the module names and so on, while the second is under Device Drivers -> USB support -> USB Gadget Support just like pietinger showed. I always use CONFIG_SND_USB_AUDIO, usually for MIDI controllers and sometimes for audio --like the builtin microphone on a USB webcam-- and I have never enabled the gadget. So I guess that agrees with how it already worked for you, and the gadget support is for another function or feature that you didn't need yet... maybe.

Yes, definitely search for things with '/' in menuconfig ! It also shows the various related options across the whole tree that would need to be enabled or disabled in order for an option to be available at all. Sometimes an option is just not even visible until all the things it "Depends on:" are lined up right. Then, it doesn't tell you where all those other required items are, so you just search for those, too.

g-virus,

sometimes I am completely blind and havent see the kernel versions.

So please take my apologize. (Yes, I am an old man). As @dbtx already wrote these are different things. Again, I am sorry.
