Hi,

I am setting up the system for streaming, and just introduced new laptop (HP Zbook 15 G6) as third NDI source.
Now I have 3 laptops as NDI sources and one main one with vMix 4K (HP Omen 17).

I am able to mute sound/speakers via keyboard on other two laptops without affecting NDI signal (i.e. used to preview/listen the audio easily), while on the new laptop if I mute the sound/speakers it also stops/mute sound as NDI source in vMix. The only workaround is to put headphones in the new laptop and use it that way, which is not ideal as I am already using another/main headphones for master computer with vMix. Also, we working in a small room with other people, so muting laptop speakers is essential.

Note: Double-checked all the settings and they are the same on all the laptops...(all laptops are using vMix Desktop Capture, etc.).
Other two laptops are Zbooks, a bit older versions. The only hardware difference I can see is that new laptop sound card is Realtek, while other laptops are Conexant ISST Audio). Got a vMix installed on Zbook G6 (potential backup) and Omen 17. If I reverse the setup, and use Zbook G6 as main and Omen 17 as source, there is no issue, as I can mute Omen speakers without muting Omen's NDI feed/input. Omen 17 also uses Realtek soundcard. Ideally I would like to use Omen as my main one (got it few days ago!).
Most likely something to do with Zbook G6 network and/or audio settings? What can it be?


Any help would be much appreciated.

Thanks.

No 'solution'. I am sorry.


I've ended up using my Zbook G6 as main vMix computer.


Note: The potential way around is maybe using external (USB) soundcard. Some, like Scarlett 4i4, have main volume control + separate volume control for headphone output. That could work.

FYI... tried it today, as I have Teams recording tomorrow where I need to record three speakers in full screen for 45min meeting/interview/chat.
(was trying/testing that NDI recording software - Livemind). Normally I do OBS screen pre-record when one speaker only, etc, with vMix desktop capture recordings as a backup. Tomorrow I will try Teams NDI output & third-party record (on a spare computer) as well as vMix NDI inputs/records.

Still the same issue with that particular laptop (Zbook 15 G6), volume/mute/sound directly controls NDI sound output as well. So I need to put it 90-100% (very loud) to get clean level/feed at the other end.
G3, G4, Omen17 all OK. No issues.

Thanks
