Has anyone else experienced audio issues when using an external interface with Mac Studio?

Hey all,

I’m looking to see if anyone else has experienced audio pops, clicks, intermittent CPU spikes and playback restarts while using an audio interface in Logic Pro. Specifically on an m1 studio, either Ultra or Max.

I’m currently on the latest version of Monterey and Logic. I’ve been troubleshooting for weeks since purchasing my Ultra and the only way I’m able to resolve the issues are if I plug headphones directly into the headphone input of the ultra and use the built in sound card for Logic.

I’ve tried four different audio interfaces (apollo x6, volt 1, focusrite 2i2, focusrite 18i20) and each one of them still exhibits said behavior, for a while I thought it was just the UA but after much further extensive testing I’ve figured out that it happens with any external interface. Either Thunderbolt, USB C, and usb 3.

Please, if anyone else has had this issue or had any potential idea of a work around I’d love to hear about it.

I am running all Native plugins, but have also recreated this issue using just the stick logic instruments and plugins.

I had zero issues for years when using an iMac - it’s only since going to an m1 that these issues have started. Everything was installed fresh here as well.

Thanks!

using a M1 Studio running Monterey 12.6.1 and Logic Pro 10.7.4 with a upgraded from FireWire to USB-C thunderbolt adapter card in Apollo 8 with no issues.

what I might suggest is to remove all unneeded external devices that attach with usb, thunderbolt, etc.. and try again.

if this doesn’t work, try logging out as you and log in as a another user. This will determine if it’s something in your user account. If this doesn’t work, then it’s a potentially a System issue.

but try one more thing would be to try and start a brand new project and test.

If that doesn’t work try changing the following and retest;

sample rate to a lower value, ie; go from 96kbs to 48kbs.
bit rate depth from 24 bits to 16 bits
or change the io buffer setting from 1024 to 512
make sure your Apollo shows the proper sample rate speed and bit depth on front display and it’s sync’s says Host, not internal

So I've just tried the last thing I could think of and I installed reaper...I've been running everything as an audio units, have been looping playback with 30 tracks plus an imported video file, a Valhalla reverb and some instances of sound toys echo boy as well, with zero issue whatsoever. No audio pops, no restarting and no cpu overloads...Using my Apollo x6, What could this mean?
