ULTRA+ Sound problem

I have the Pi Zero 2W and install the ULTRA ++ Audio HAT.
The instalation finished without problems.

I have a problem with the audio quuality. When i use the onboard mic to take a record file the quality is ok.
If i use the “Line In” jack with some music and play it over the “headphone jack” you only hear some bits. It seems like a oversteer audio signal.

I need to use the Mic jack oder Line in Jack to put in audio files like Music.

  1. I am nott sure if the installation / config is correct because if i start “pavucontrol” i can switch between headphone and speakers in the output menu. In the input menu i only see the onboard mic not the Mic jack. i cant choose the Mic Jack as input.

Can somebody help me ? :slightly_smiling_face: :slightly_smiling_face:

Hi

Have you just tried to change the volume settings in alsamixer?

sudo alsamixer

press F6 to select the card

I had trouble with the instalation (dkms tree + kernel error) but now i think the installation works.
With alsamixer i switch on the MIC Jack (… LINPUT 3) and LINE IN Jack (LINPUT 2).
I can hear a sound but the qualitiy is bad .When i play a short mono sound the quality is very bad.
