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

cat /etc/asound.conf

  }
}

}

pcm.postmalsa {

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]

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]

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]

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:

Volumio 3 Buster Beta for RPi

Installed the beta to address the crackling issue I had with my cheap Adafruit MAX98357. After some help from @Timothyjward the crackle is completely now eliminated. I can echo the previous post that responsiveness is much snappier. One thing that is missing are the UK’s national BBC radio stations are not available under the web radio tab - Which means no BBC 6Music, which is what is usually playing on this particular volumio speaker. Sys info: Volumio 3.046 Raspbery pi 3A Adafruit MAX9835…

[balbuze]

hum, and it doesn’t work? asound seems correct.
To update, go to IP/dev as described here : System updates - Volumio Documentation

[supercrab]

3.051 is the latest version for me?

[Lintbf]

Enter in test mode from, volumioip/dev then go to system update and do the update. Or a factory reset if integrity check fails and try again.

[balbuze]

have you enable test mode as explained in the link above ?(scroll down)

[supercrab]

I have now! I didn’t know about test mode, upgrading now. Exciting…

[supercrab]

The error message when playing mp3s has gone but the analyser still doesnt work.

[Lintbf]

I have noticed that when using spotify mpd oled does not show bit rate in upper right corner like on we radio. On qobuz it was shown when I had s subscription on volumio2

[balbuze]

yes, you’re right. II tested Spotify and Spotify connect ans spectrum is working fine though

[Lintbf]

Pls give me a link to install the spotify connect.

[balbuze]

from my repo : https://github.com/balbuze/volumio-plugins/raw/alsa_modular/plugins/music_service/volspotconnect2/volspotconnect2.zip

[Lintbf]

Because last time when I had install, it was not working and astephy said to add some code… But I will instalk it again. Thanks

[supercrab]

Bah :’(

[supercrab]

No bit rate is probably because spotify does not use MPD.
Bitrate info comes from MPD.

[Lintbf]

Then but why spectrum can be shown? I know that in volumio2 the spectrum is not shown because of the specific daeomn used for spotify, but in volumio3 the spectrum is shown with this alsa implementation
