Public bug reported:
First I must say you, my English is not very good. I'm from Germany and I
learned English in school, but this was in 1986.
*
My notebook:
Product Name: SCHENKER_DOCK_15_SDO15L18_SDO15E19;
Board Name: Clevo N350TW;
Dual-boot: "Linux Mint 20 Ulyana (based on Ubuntu 20.04)" and "Windows 10
1909";
Architecture: x86_64;
Kernel release: 5.4.0-40;
Audio device: Intel Corporation Cannon Lake PCH cAVS [8086:a348] (rev 10);
Subsystem: CLEVO/KAPOK Computer Cannon Lake PCH cAVS [1558:0351];
*
Here is the problem:
When I boot Linux, the notebook have no sound from speakers and headphones.
When I click the speaker-icon in tray, I can only see "Dummy-Output".
Sometimes I hear a crack from the speakers.
Only when I connect the notebook and the TV with a HDMI-cable, I have sound on
TV.
When I now click the speaker-icon, I see "HDMI-3".
This problem was also with the Live-CD and also with "Linux Mint 19.3 Tricia
(based on Ubuntu 18.04)".
If I boot "Windows", there are no problems with sound.

Can someone please help me to solve this problem?
My Linux skills are average (learning by doing).
Thanks in advance for your assistance!
