[PROBLEM] Volume goes to Zero on change

[DRONE7]

I did a few tests unplugging my Revolution DAC which has a small display that shows the volume in dB and no issues with moOde or the DAC volume being reset to 100%.

What model DAC are u using?

If another user has the same model perhaps they can try and repro your issue.

DIY DAC on ak4490, but the most important part responsible for the volume is the USB converter - XMOS DIYINHK. 


I forgot important information. After starting the DAC moode shows the previous level of the dash in steps 1-100. Eg 11 which correspond to -58dB. The problem is that instead of showing -58dB then it is 0dB. I enter the ALSAMIXER, and it really is 0dB. I click +, step 12 appears and the volume is -56dB. Magic...

IIRC there are/were 2 versions of the DIYinHK XMOS XU208. One had some firmware that interfaced volume control on Windows based systems and the other didn't.
The second version worked with linux  the first version was flakey with Linux.
Is yours an XU208?

Later versions XMOS XCORE-200 XU216  didn't have that problem.

I will see if I can find some info.
