I'm trying to record on my PC at the same time as my laptop, using wifi for the PC and my phone's data, hooked through a sound mixer to the laptop.  I have no problems with video and audio on my PC. However, the guests' audio will not play through the cellphone to the laptop, although this connection works whenever the PC is not included.  How do I use two separate simultaneous devices while using wifi for one and data for the other, so as to secure a backup recording if one or the other were to be disrupted?

Hello,

First of all, I apologize for my level of English.

I'm having a problem with the Zoom software and the sound is choppy and hard to hear.
This only happens when the person I'm on video with is playing music on Spotify, for example. I can hear his or her voice just fine.
I'm the only one with this problem. The other people taking part in the conference have no problem and can hear the music just fine.

I encounter this problem in the following situations:

When I use headphones that I plug directly into the computer.
When I use headphones connected to my external sound device.

But I don't have this problem when I use the laptop's speakers.
It also works when I use Zoom Web Portal (with or without headphones, with or without an external sound device).

The Zoom software is up to date.
Windows is up to date.
My sound device (Presonus Audiobox) is up to date.
My laptop sound device is up to date.

I also activated "sound for musicians" in Zoom, without success.

My computer is an Asus vivobook laptop, with Windows 11.

Thanks to anyone who tries to help me!

Hola, intento compartir audio de mi mac en mis sesiones y me dicen que se escucha perfectamente pero mi voz no, suena entre cortada o a veces un poco robotizada, pierde calidad. Utilizo micrófono condensador USB. 

Apunte: 
En la configuración de audio tengo activado el filtro para sonidos externos tipo ladridos de perros. 
 

Me podéis ayudar?
