Hi,
I freshly installed Raspbian 10 Buster Lite and did a full "apt full-upgrade".
cat /etc/*-release PRETTY_NAME="Raspbian GNU/Linux 10 (buster)" NAME="Raspbian GNU/Linux" VERSION_ID="10" VERSION="10 (buster)" VERSION_CODENAME=buster ID=raspbian ID_LIKE=debian HOME_URL="http://www.raspbian.org/" SUPPORT_URL="http://www.raspbian.org/RaspbianForums" BUG_REPORT_URL="http://www.raspbian.org/RaspbianBugs"
aplay -lL" outputs:

BUT after starting Alsamixer, I am getting following error on dmesg:
[ 1179.134492] ma120x0p 1-0020: ASoC: error at soc_component_read_no_lock on ma120x0p.1-0020: -121 [ 1179.135458] ma120x0p 1-0020: ASoC: error at snd_soc_component_update_bits on ma120x0p.1-0020: -121
Alsamixer shows the controls of the snd_rpi_merus_amp but when I want to set the volume, limit etc, the values will be locked to huge values /maximum values and I cannot change them at all. See alsa/asaound.state:

Sound is also not playing.
Do you have any solution? Thank you very much.
