[How to do instruction] 128x64 OLED with Song Status and Spectrum Display on Raspberry Pi

[f.omar]

Hi f.omar

Thank you for posting the output from the commands.

The issue appears to be that you are using 'hw:Loopback' instead of 'plughw:Loopback', and I am able to reproduce the freeze here.

If you install mpd_oled with the following command then this will hopefully fix the issue for you

Code:

sudo mpd_oled_service_edit -o 1 -b 10 -g 1 -f 20 -c alsa,plughw:Loopback,1

I have reviewed the current install instructions for mpd_oled on Moode and they say to use 'plughw:Loopback', but older instructions said to use 'hw:Loopback'. (I can see the mpd_oled_moode_audio_copy_install script says to use 'hw:Loopback, but this script shouldn't be run on Moode 7.2.1., and 'hw:Loopback' worked fine on 7.0 and 7.1)

Please let me know if there are any changes I could make to avoid this happening for other people.

Adrian.

Hi Adrian
I ran the command. It still freezes.
