Hello,
I'm also reporting that I don't have any bar showing. During installation Code: mpd_oled -o6 -c alsa,hw:Loopback,1bars were showing. But after with mpd_oled_service_edit, I enter -o 6 -b 10 -g 1 -f 20, then no bar. I tried -o 6 -a 3c -b 10 -g 1 -f 20, no bar. -P s is working, when paused it goes back to big clock. I tried from installation from source, same thing.

Hi officialsm
Thank you for posting the results of the commands. Everything appears to be configured correctly. The loopback device appears to be setup correctly, the ALSA configuration file looks fine. There is, however, one strange result, which is that Moode is saying that your volume is 0 Code: pi@Simoode-audio:~ $ cat /var/local/www/currentsong.txtI wonder if no bars are showing because the audio level is too low when the audio copy is made. Could you try to adjust your volume so that Moode reports a value for it, and see if this helps with the spectrum bars. Adrian.
03-22-2021, 03:24 PM
Hi Alain
You need to specify the loopback device as the audio source, and so your installation command would be Code: sudo mpd_oled_service_edit -o 6 -b 10 -g 1 -f 20 -c alsa,hw:Loopback,1I will update the installation instructions when the method has had a bit more testing. Adrian.

Tried to change to software audio mixer but still not see bars. Thank you so much helping me. I will try again when i will reinstall Moode.

Hi officialsm
Sorry it hasn't worked out. Hopefully a solution will present itself when I have had some more feedback. Adrian.

Hi officialsm
The disabled mixer does not seem to be a problem. I usually use an I2S DAC with software volume. Without changing the audio copy configuration, I changed to mixer type disabled (0db outout), and the spectrum worked fine. I then plugged in a USB DAC and tried the software, hardware and disabled mixers, and in all cases the spectrum worked fine without any changes to the audio copy configuration. That led me to review your ouput again, and I think I have found the problem! Code: pi@Simoode-audio:~ $ ps ax | grep mpd_oledYou are running mpd_oled without specifying the loopback device as the audio source. In which case, make sure you do not have a copy of mpd_oled running and then run Code: mpd_oled -o 6 -b 10 -g 1 -f 20 -c alsa,hw:Loopback,1Adrian.

So it started as old package. Now it is fixed and working. The trobule is that now it doesn't start at boot. I have to run each time the command from prompt. How can i enable it at boot? Thank you |
