ugreen USB Sound is not recognized by alsa

Post by muecke77 » 2021/01/30 09:58:30

Hello,

I have a pc-engine apu2e4 board and a ugreen usb audio adapter. Last Centos7 is installed and fully updated.

lsusb shows
Bus 002 Device 002: ID 0bda:48f0 Realtek Semiconductor Corp.

snd_usb_modules is loaded. lsmod gives

Code: Select all

lsmod |grep snd

soundcore              15047  1 snd
anyway aplay -l doesn't find any card
aplay: device_list:272: no soundcards found...

Any idea would be highly appreciated.

Thanks

One additional information: When I plugin the USB-stick, the following messages show up in /var/log/messages

For me, it looks really ok. Any idea, how I could dig deeper?

Code: Select all
