Hi Phil,


Looks like incompatible bitrate (default is 16bit) with DAC:

shairport-sync.service - Shairport Sync - AirPlay Audio Receiver

IF you are using the Allo GUI, you can change this in the web interface. If not, simply run the command to change to S32 output:

sed -i '/output_format = "/c\output_format = "S32";' /usr/local/etc/shairport-sync.conf
dietpi-services restart


Hi Dan

Perfect !

I was a bit doubtful… I saw 32 bits several times through software but DeqX is only communicating on 24 bits. And I think I unsuccessfully tested this setup with Allo Web distro. However, I installed back the DietPi distro 2 days ago and tested this parameter with success.

Thanks very much !

Hi Dan

I am about to acquire an Allo Digi One signature with the Allo + Dietpi. Can I check something please. I am planning to use it for Roon but also Spotify (plugin). If I also install the EQ plugin, will things work or will there be a conflict with Roon?
In other words, will Roon bypass the EQ Plugin without issue?

(Vincent Kennedy) #208 @rahulkc just attempted to purchase a usbridge from your website and when I added it to my cart I received this message: " 1. There is no stock available for this selection / item. Please choose something else, or come back soon to check availability."

Do you know when these are going to be back in stock? I am fairly certain that I am not going to go back to your site every day to see if I can make a purchase. I was really surprised I wasn’t asked if I wanted to be notified when they were back in stock.

End of this week.


How do I go about getting the lcd screen attached to show what is being played via Roon/Spotify/UPnP Player? Right now all I am seeing is boot screen.

I have this image installed on Pi + Kali + Allo Piano 2.1.
Piano is setup in Dual Mono mode.
The volume is very low at 43%.
I increase it with Alsa via the master volume, but the behaviour is unpredictable.
Using the Roon remote volume control sometimes shuts of the right channel.
Also the sound quality is different , when for example alsa is at 43% and I increase the amp volume Vs I increase the volume via Roon remote.
Any thoughts, how can we increase the volume on alsa and store it permanently ?
