Sound on Roon with card "none" but no with squeezelite !?!

Troubleshooting
1

With my Allo USBridge and last version of Dietpi (6.22.3), i have sound on my dac (Audio-GD with amanero card) but with card “none” (previously USB-dac 1.1) ?! (“none” on Allo web interface and dietpi-config too)
I’m happy… i have sound with Roon but no output with squeezelite.
If i choose another sound driver (ex. usb-dac 1.1), squeezelite service crash.
With card “none”, i have sound, but i think squeezelite conf has not the good output.

It works if i stop Roon and in a terminal launch this command :

root@DietPi:~# squeezelite -o hw:CARD=Amanero

But no possibility to make a good and stable configuration with dietpi-config.

Many thanks for your report.

Which device do you use? Ah if usb-dac-1.1 is available it must be Sparky SBC right?
And did it work before with an older DietPi version and when selecting “usb-dac 1.1”?

I wonder that “none” works for your since this should add hw:0,0 (card 0 device 0) to your asound.conf which is as of your output the analogue 3.5mm jack which should be disabled.
The USB DAC is hw:1,0 which should be auto detected when selecting usb-dac.

Now I wonder why you can actually choose “none” since this is only available on RPi :thinking:.

Please verify which SBC you use and paste:
echo $G_HW_MODEL
cat /etc/asound.conf

  • At best the above once when selecting “none” and once when selecting “usb-dac-1.1” (even that those two options should not be visible on the same device). And then if there is an output through the DAC.

Thanks for reponse.
It’s an AlloUSBridge (Sparky) whith AUdio-GD DAC via Amanero USB port

root@DietPi:~# echo $G_HW_MODEL

root@DietPi:~# cat /etc/asound.conf
pcm.!default {
    type hw
    card 0
    device 0
}
ctl.!default {
    type hw
    card 0
}

I am confused … I tested usb-dac, it works.
I had not tried because before I was on usb-dac 1.1.
And now it works also under squeezelite.
Squeezelite reads dsd files without any particular plugin.
But I do not know what are the options built into the squeezlite config and what is sent to the dac for DSD.

root@DietPi:~# cat /etc/asound.conf
pcm.!default {
    type hw
    card 1
    device 0
}
ctl.!default {
    type hw
    card 1
}

Dop with downsampling ?

Ah this makes sense. usb-dac-1.1 adds a kernel cmdline option to force the USB speed to 1.1. This is only required and should be only used if the USB-DAC is known to be incompatible with other USB speed modes.

About the DSD to be true this is out of my knowledge as well :wink:.
