Hi, I can’t get sound out of the C2.  
I tried [https://dietpi.com/forum/t/resolved-no-sound/51/1](https://dietpi.com/forum/t/resolved-no-sound/51/1) but when trying to play a file, I get “sample format non available”. Might be an issue with the downloaded wavs. Do you have a file that should work?  
When trying

```nohighlight
amixer scet numid=3

```

the answer is: amixer: Cannot find the given element from control default.  
Edit: HDMI cable and monitor work fine on Windows-PC and with Raspi 3.

Hi,

I’ll check the bug report, thanks.

Can you test the following and see if sound works, paste results if error:

```plaintext
speaker-test -c2

```

Looks like speaker-test is running fine. You should have sound.

Most likely HDMI cable or TV configuration. Try another HDMI cable, and TV if possible.

Hi Fourdee,

Thanks for your support. I double checked the cables and monitors. They work fine with Windows or my Raspberry.  
I checked libreelec on a second SD card and Kodi gave the clicking sound 🙂  
So I tried to install squeezelite and got the “you are offline, because debian is not available” message. So I changed to the UK-Location, installed squeezelite and updated to version 145.  
Now the C2 is playing music from squeezebox or from my iPad 🙂

Don’t know what really caused it.
