Hi all, first post. 

I'm going nuts. My son has guitar lessons with a guy in the US. We are in the UK. In order for the lessons to occur, he needs a mic to talk.. his guitar signal and the DAW playback all to be heard at the same time. 

He plays through a helix floor pedal, straight into the focusrite Scarlett 18i8 interface. The mix is also plugged into a line input on the interface. 

The problem is this.. I can play back everything at the same time when testing the mic input in zoom settings. However, it feels like there is a signal issue with the guitar. If he plays continually, the signal continues fine. However, if he stops for a bit to talk/listen to his teacher, the signal can take a while to be read again buly zoom. Sometimes like 10 seconds. Sometimes it comes back only partially and muffled but then kicks in and the line goes green again. If I run it next to my Mac input signal.. there is no delay, only when going into zoom. 

Sorry if this is a bit garbled. I'm at my wit's end and can't find any solutions online. If anybody has any ideas? 

Thanks in advance,

Mark

Good day,

I tried to link my presonus audio box usb 96 with zoom on my dell inspiron laptop so that I can use two external microphones but only one of my microphone channels are being recognized even though windows recognizes both channels, did anyone ever experience this problem?

I need to see all participant boxes in my gallery view recording, even those who have no video up.  I just had a recording with 15 people and a bunch of them did not have video up, but they occasionally spoke.  I can't tell who is speaking because none of their boxes appear in the gallery view recording.  I have "Hide Non video participants" unchecked in the app.
