Razer Audio Mixer video freezes

Hi all. I had the following problem. I bought a Behringer UV1 mic preamp (similar to DBX 286s) and when I connect it to a razer audio mixer I get a constant loud noise. I've already connected it via XLR and TRS Jack 6.3 and it's still noisy. Moreover, this is not even background noise, but noise at the same level as my voice. If I connect the Behringer uv 1 preamplifier to my PC and connect headphones to it, the sound is excellent, but as soon as I connect it to a razer audio mixer, loud noise and interference immediately appear. I've already tried changing XLR cables - it's not the problem. I think it's the mixer that's the problem.

Update from me:

Windows 11 pro: All updates

Faststart disabled

Razer Synapse Version: 20240229

Problem is fixed.

I know there is an update for the synapse software, but I don’t want to risk it getting broken again.

How does disabling fast startup fix this problem? Doing it now…fingers crossed!

Edit - It doesn’t fix the problem. Audio still will lag causing issued with videos to either stop entirely (e.g. YT) or cause the video to buffer while the audio persists in which having to mute the video will let the video catch up to the audio….this is frustrating to say the least.

i am having this issue and have found that using the restart audio drivers function on the customize tab replicates this issue. i suspect there is an automatic/scheduled prompt to restart audio drivers that messes with video encoding in session. 

Thanks i will try this because i have the audio mixer since almost 1 years and half and the issue is not fix yet. Since 6 months i unplug it.

Razer support is always nice but for this product it sucks… i talk 6-7 times to support and the only solution they give me it’s to send them my logs… after 1 years of support it’s always unfix. I ask a refund for malfunction and they didn’t want before find a solution and send them again my logs --'
