i need to drive the sound out- and input over my external usb soundcard for some speech recognition.
I am using raspbian stretch and the soundcard is the following from Ugreen.
https://www.amazon.de/UGREEN-Soundkarte ... B016CU2PEU
I searched the entire internet and couldn't find a solution for hiring Alsa to activate the soundcard.
The approaches for raspbian Jessie and Wheezy were unsuccessful and were not applicable because folders or conf-files do not exist.
If there are questions about my system or setup feel free to ask.
I hope someone could help me and i would be very thankful.
Thank you and i wish you a nice day
