Only Dummy Sound Output

[haschdag_baum]

Hello,
my problem: I only get the Dummy Audio Output with the Internal SoundCard. With external SoundCard (my USB Hub has a 3.5mm jack) is it all fine. The System dosn’t detect the internal SoundCard. It isn’t listed in ALSA. But with “lspci” i see my SoundCard. And also the SoundCard workes fine under Ubuntu 20.04 and Windows.
I am completly new at Arch based Distributions.

Thanks in advance

If you need it, I am using:
Manjaro with KDE (Software is up to date)
Lenovo Yoga C740 (SSD UEFI encrypted, but without encyption it also dosn’t work)

To allow all of us helpful people on this forum TO HELP YOU, we need some basic information about your system.

Hello haschdag_baum,
could you try
arecord -l
in a terminal to see if it shows up as a sound card there?

For me it is
[julius@Pinebook ~]$ arecord -l **** Liste der Hardware-Geräte (CAPTURE) **** Karte 0: rockchipes8316c [rockchip,es8316-codec], Gerät 0: ff890000.i2s-ES8316 HiFi ES8316 HiFi-0 [ff890000.i2s-ES8316 HiFi ES8316 HiFi-0] Sub-Geräte: 1/1 Sub-Gerät #0: subdevice #0

found the command here

Best Regards, Julius

is your USB Dac, I believe. Please correct me if I’m wrong

It doesn’t seem to show up, unfortunately.

• Do you know from what vendor your sound card is from? Maybe some are experiencing similar issues with this.
• lspci makes it show up, so it should be connected to the computer. Following this guide, you could try sudo alsa force-reload, exit with Ctrl+C (oder Strg+C für die mit einer deutschen Tastatur), and reboot.
  The guide also shows other methods and I would recommend that you look at it since most should work even if the guide was written for ubuntu, originally.
  Best Regards, Julius

Hi,
yes, that is my USB Hub.

I tried “your” guide and the fifth point (for the Lenovo Carbon X1) worked.
I created there the file and reboote.
Now I have sound.

Thank you a lot
