can't configure 9.0.5

[livingvoice]

Your problem discribes exactly what I encountered when using an Allo Piano 2.1 dac.
So what is your actual configuration?
In the last line of your message I see:"RP3 & 4, Dac USB Chord Quest or AudioNote DAC1 or AlloDac + préam Yaqin MS_12B + Tamp S75 MKII + LivingVoice Avatar II  "
I particular the Allodac, is this an Allo Piano 2.1?
If you are using a Piano 2.1 than your problem is caused by an incompatible driver from Allo and the highest Moode version you can use is 8.3.9. Versions 9.x.x are based on a new version of Raspberry OS when chokes on the old Allo drivers

Hi Sunfish,

i start without DAC, only RP4 board; i would like configure my USB Chord Quest (mainly DAC) when i can access Audio menu.

i note your remark about AlloDac and version 9.0.x

thanx
