I bought a dedicated DAC/Pre amp and HP amp a few weeks ago I'm using in my dedicated system. Lately,  I'm finding that when I try to get it to play, I'm not getting any sound. If I power it off and then back on, it works. I happens sporadically. Any thoughts?

What's the DAC?  How are you feeding it?  USB, coax, or optical?

It's a Nuprime DAC 10-H (DAC/pre amp/HP amp) using as part of a dedicated speaker and HP system. I'm using digital cables between the DAC and a CDP and a Sonos connect and RCA to a power amp. I’ve swapped in some new digital cables. I’m wondering if there’s something going on with the connection.

It's probably losing lock as some DACs do without a stream. Next time toggle the dig inputs if possible. Shouldn't take a reboot but a modern dac should also lock with strea even if it unlocks without. I doubt it has anything to do with the Sonos. They're generally solid and non-tweaky.

Since it's not USB, the chances of having data stream issues are greatly reduced.  Does it have a mechanical mute?  As mentioned above, it's likely losing a data lock, and it is probably the fault of the DAC, or a mechanical mute is sticking after there was a change in the source files--bit rate, etc.  Either way, it sounds like the DAC is at fault and you may want to contact the manufacturer.
