USB audio dropouts on Big Sur 11.3

Since I've updated Big Sur to 11.3, I'm having massive problems with short audio dropouts through my USB audio interface (Roland Rubix 22). The dropouts occur at least once a minute (mostly 4-5 times a minute) and it makes both listening to music and my professional audio work in Logic Pro X impossible, which is very frustrating. I've isolated the problem by testing my hardware and cables on different machines. It all works fine (as it did before 11.3). So it has to be the update.

I'm not alone with this problem:

I hope that there are more people with that issue, so Apple will listen and fix that.

I'm on a MacBook Pro M1.

UPDATE: Unfortunately, the update to 11.3.1 did not fix that.

I contacted apple support about this. As I expected, apple rejects any errors and should I contact the manufacturer of my sound interface. Very disappointing.

No you are right, but the only solution right now,

Has it been fixed in Big Sur 11.4?

May 24, 2021 10:34 PM in response to steffen280

Sadly not. 11.4 is stuttering just like 11.3. My hopes were dashed. 😢

I installed 11.4 yesterday, from 11.2.3, and something they have changed, for my problem has disappeared.

Updating to 11.4 seems to have solved the issue on my MacBook Air M1. No dropouts anymore. (Presonus AudioBox iTwo with Logic Pro 10.6.2)

I upgraded OS to 11.4 a week ago. Since then I have not experienced the issue I had with 11.3 so far on MacBook Air M1. My USB audio device is USB DAC SMSL SU-9.

That is great news. Sadly I'm now waiting for the next update to see if my stuttering USB 2.0 audio output problem is fixed. 🤞

Sadly 11.4 hasn't helped my problem. Still stuttering output through my USB dac.

Sadly my audio output via my USB DAC is still stuttering on 11.5. So frustrating.
