Zynthian (Raspberry Pi 5 + PCM5122) Audio Quality Issue and Click Noise on Note Stop

Using Zynthian
1

Hello everyone, I am using Zynthian with Raspberry Pi 5 and the PCM5122 Audio Board

config.txt (3.7 KB)

for audio output. However, the sound I get lacks detail and spatial depth. With the same file and the same headphones, playback from my computer sounds noticeably more detailed. This applies to both SF2 and SFZ files. Honestly, when I listen on my computer using a Focusrite Scarlett Solo, the sound is still fuller and more detailed.

I understand that this comparison may not be entirely fair, but I would like to ask whether this is a hardware limitation or an issue with my configuration.

Additionally, when I stop playing a note, there is a slight click sound just before the audio fully cuts off. Has anyone experienced this issue, and is there any way to resolve it or any alternative solution?

Thank you, and have a nice day.

Try using your scarlet with zynthian. That will rule in/out the soundcard.

The clock is likely to be an automate iIRC the PCM5122 had a mute circuit that may be disabled with a jumper.

[Edit] The 5122 also had a filter that may need to be disabled.
