Major Distortion all of a sudden

Studio
1

I have been happily using Studio several months and have not had any problems until today.

While streaming Qobuz, it will play a few songs and then all of a sudden there will be very load garbled distortion. I have not changed any settings for several months either.

This is not a one time occurence, as I closed Studio when it happened the first time. I thought it may be because it was open for nearly a week. I restarted it and after a couple songs, it did it again on a different album.

Any help would be greatly appreciated,
Here is a debug, directly after occurence:

Have you tried to reboot your DacMagic? DO you know if there has been a firmware update of it recently?

3

I have not did anything other than turning it off and on when using and not using. I am not sure how to reboot.

I have not updated the firmware.

DISABLE Integer Mode on your Mac - its disastrous implementation has always been the source of distortions and even random reboots on Mac.

Hi @briawyer,

The settings in Audirvana show that Integer Mode: OFF already.

Edit: That was before I turned on my DAC. Turned it off now.

I also reset the DAC as suggested by @Antoine

Going to give it a run now.

Thanks

So far so good. I got through an entire album, one of which was messing up yesterday.

…and to add, when it was messing up yesterday, 3 times, only Studio was running. Today, I was putting it to the task. I had many things going, fully stressing out the system while listening and no mess up.

If all goes well for a couple more, I will mark this as resolved.

Thanks all

You’re welcome.
