Using a MOTU UltraLite DAC - will it work?

[philrandal]

Hi

I bought an MOTU UltraLite mk5 to handle multichannel output (Main L/R, subs, zone 2 L/R) but I fear I've run into an incompatibility with moOde. From what I've read, the MOTU DACs need a kernel version 5.11 or higher, and since moOde uses 5.4 I'm not getting any output - not even simple stereo before I try anything more complex. Curiously Roon can see the DAC, and sending a stream to the DAC from Roon or the moOde GUI causes the MOTU to report on its screen that it is locked to the appropriate sample rate, but no stream is actually received.

The DAC sounds wonderful in other configurations, suggesting the problem does seem to be incompatibility with moOde, which is consistent with what I've read. I've Googled in vain to find a patch, but before throwing in the towel I thought I'd ask in case anyone has successfully got a MOTU DAC working with moOde.

If not then the plan will have to change, which would be a shame - I really wanted to use the moOde GUI for Camilla, but that may simply not be possible.

Thanks

Kernel 5.11 or newer? 

Drat, the soon to be released debian Bullseye (and Raspi OS bullseye) come with kernel 5.10.52.

Cheers,

Phil
