Hi Adrian

i see when i rotate 180 degrees with command
sudo mpd_oled_service_edit -o 1 -b 21 -g 1 -f 20 -c alsa,plughw:Loopback,1 -R

sudo mpd_oled_service_edit -o 1 -b 21 -g 1 -f 20 -c alsa,plughw:Loopback,1 -P s does not work any more

thanks

Hi Jempie

The options you specify with mpd_oled_service_edit are the options that will be used with mpd_oled. Your new command needs to include both '-R' and '-P s'. It could be

Hi Adrian,

after a will playing it give MPD error Failed to open audio output
RPI 3b / Moode 7.4 / dac Audiophonics 9038

what could it be

thanks
Jem

Hi Jempie

If it works well for a while and then you see the error it doesn't sound like an mpd_oled misconfiguration. It might be worth asking in the Moode support forum (give as many details as possible about your hardware and the steps that produce the error).

... or start all over again by installing a fresh new MoOde build with the latest MoOde version... and test JUST the mods required by the installation of the OLED screen...

Hi Adrian,

I have after playing hours MPD error, Tim told me to set "The DAC may only work in moOde when ALSA output mode is set to "Direct (hw)"
but I cannot set into Direct(hw) and Loopback on

thanks
Jem

Hi Adrian,

i have done the following (sudo systemctl stop mpd_oled)
and select output mode Direct (hw)

now i have no MPD errors but also no bars in the display

Hi Jem

If you cannot set the ALSA loopback to 'on' then a copy of the audio is not being made. However, mpd_oled/cava needs a copy of the audio to calculate the spectrum bars, and so if there is no copy of the audio then there is no spectrum displayed.

If you use the original Moode ALSA setting (not Direct (hw)), is there a series of actions that reliable produce the ALSA error? I am not sure if you have described when the error occurs, e.g. when you restart the machine, or when you play the first song after a restart, or when you play a certain music file, or when you change music sources to MPD (e.g. from playing spotify to playing a music file)... If you provide a clear description of when the error occurs perhaps somebody will be able to suggest something for you to try or investigate further.
