Resolve 17.4 no audio out to Intensity Pro 4K

PostSat Oct 23, 2021 4:57 pm

With the last update (17.4) I lost audio via hdmi out with Intensity Pro 4K.

I did not have this problem with the couple of last versions.
I rolled back to 17.3.2 to confirm and isolate issue and my audio via hdmi came back ok.
Updated again and checked Resolve preferences if I have the same settings, confirmed audio is not coming out only after 17.4 update.

The audio meters in resolve show audio is there, also audio is available with PC usb out.

Could this be DESKTOP VIDEO issue?

After updating to 17.4 I also tried reinstalling Desktop Video (ver 12.1) just to see if it will "nudge" back audio but no go.

Is this isolated to HDMI or also via the analogue outputs?

I just tested the analog (RCA) out and it also will NOT have audio with ver 17.4.
It works with 17.3.2.

yes, I saw that too John.

I think something broke with the Desktop video drivers when the 17.4 was rolled out. Waiting for a fix on this, and meanwhile I'll stay with 17.3.2.

There is a new setting in 17.4 in audio preferences, to mirror audio to the video i/o and audio interface, allowing you to enable both across Fairlight and all pages. It defaults to being unchecked and HDMI audio is disabled, so you can use only the audio interface for everything, which wasn't possible before. If you check it, it works as before and your hdmi audio will be restored, at least here on an US 4K Mini.

You're welcome Ted and it wasn't documented. It's a great new feature though amongst many others.
