[NOT RECOMENDED!] Plugin and Tweaks Adventures on Buster Betas

balbuze · March 10, 2021, 9:01pm

Peppymeter is not using loopback. I think we can make both working together. But it probably need some adjustments… Peppymeter use a special pcm device"meter" to pipe data. But in my plugin I use a route to make it work with other plugins such as equalizer or DSP. @supercrab have you made other mod on the system?

supercrab · March 10, 2021, 9:07pm

Ah, cool! Yeah, I shouldn’t really speak about things I know nothing of

I haven’t made any other mods. It was a fresh install yesterday. I didn’t want to introduce to many changes.

You can’t have the clock displayed if the plugin is disabled. I noticed my clock would not clear but it seems to be working as it should now…

Lintbf · March 10, 2021, 9:17pm

now the plugin is disabled and the watch is displayed , for me this is ok

supercrab · March 10, 2021, 9:20pm

Is the clock actually refreshing? What happens if you play music? I think the screen might just be stuck on whatever it was displaying…

Lintbf · March 10, 2021, 9:23pm

yes you are wright it is stuck . is just late I guess but it will be great to make it work in paralel in the newr future . Because it is nice plugin and my streamer is build with an oled display just because if this .yo show watch when not playing .
Thanks

I retested the version of mpd_oled I uploaded above on a fresh install Volumio 3.054 and it works out of the box
edit : I added an equalizer, still ok
webradio, qobuz, nas ok

Lintbf · March 11, 2021, 6:18pm

The same for me, on 3.054.

Lintbf · March 12, 2021, 6:09pm

Hello,
Mpd oled : when I am listening to spotify and stop the song the screen is not switching to watch screen. I know that it was an issue also with qobuz but it was fixed. Now I guess this is an older version of mpd oled. I guess it was fixed by adding p suffix something like this to. /mpd_oled command
On web radio is ok.
Thanks.

Lintbf · March 12, 2021, 6:30pm

It was this option
I will check if this is working with this mpd oled version because it has involved also a change in the code.
The line in mpd_oled.service might look like

ExecStart=/usr/local/bin/mpd_oled -o 6 -b 21 -g 1 -f 15 -P s

supercrab · March 12, 2021, 7:11pm

Ok, thanks for testing! I’ll try a fresh install…

supercrab · March 12, 2021, 7:19pm

You need to change this in the plug-in config screen. Might be called pause screen or something.

balbuze · March 12, 2021, 7:21pm

Yes, I had the problem too. Fixed in plugin setting

Lintbf · March 12, 2021, 7:37pm

Thanks. Found it.

@supercrab
weird. Can you share /etc/asound.conf?
what aplay -L returns?
my asound.conf

cat /etc/asound.conf 
pcm.!default {
    type             copy
    slave.pcm       "volumio"

    pcm "toLoopback"
    format "S16_LE" 
    rate 44100 
    channels 2
  }
}

pcm.toLoopback {
  type hw
  card 'Loopback'
}

pcm.postmalsa {
  type copy
  slave.pcm "postalsa"
}

pcm.postalsa {
    type             copy
    slave.pcm       "volumioOutput"
}


# There is always a plug before the hardware to be safe
pcm.volumioOutput {
    type plug
    slave.pcm "volumioHw"
}

pcm.volumioHw {
    type hw
    card "Headphones"
}

edit : please update to v3.054

balbuze · March 13, 2021, 9:07am

a problem I see, after a boot, before playing, a clock with a wrong hour is displayed, no IP adress. Maybe the trick is to delayed (few seconds) the display when volumio boot
When disabling the plugin, the display remains on , but stuck

Lintbf · March 13, 2021, 9:54am

I have observed that when disable or enable mpd oled or peppy I hear some cracks in speakers. I think it is with pepy but I will check…

supercrab · March 13, 2021, 10:47am

I just noticed I’m not on v3.054 - I’ll upgrade to that version. I thought I was on that version.

I can’t find the download link for 3.054

I’m looking at this page for the beta:
