If you're trying to record or Zoom meeting with a clean line-level audio into a USB-C iPhone (15–17), here's the setup Apple doesn't tell you about—but it works beautifully:

🔧 What You Need

• Mixer or Line-Out source (e.g., audio interface, soundboard or line-out from a sound system)
• 3.5mm cable (from source to where your Zoom is on your Iphone)
• Variable attenuator (e.g., Nano Patch+ or SESMKP-27)
• SR-C2003 cable (3.5mm TRRS to USB-C)
• USB-C iPhone 15–17

🚫 What to Avoid

• Apple’s USB-C to 3.5mm adapter — DAC-only, output only, no analog input support.
• Fixed attenuators like Headset Buddy — Only works with lightning connections.

✅ Why This Works

• USB-C iPhones accept analog input via TRRS when properly wired.
• SR-C2003 cable is TRRS-compatible and routes signal correctly (supports microphone or line-out type).
• Variable attenuator lets you match mixer or line-out output to iPhone input level (you control the level of attenuation).
• Apple doesn’t offer input gain control—this setup solves that.

🧠 Bonus Tip

The Nano Patch+ or the SESMKP-27 (or similar attenuators are passive, durable, and gives you smooth rotary control over your input level.

I use to be able to add another session in my recurring meetings by just clicking on the 'add another session' button. Something has changed as the option is no longer there. however, all videos and responses from the service ticket just keeps to go to your recurring meeting and click the button to add a session which is very unhelpful if there is no button there to click. Has anyone else had this issue and found a workaround? So far, I have had to add multiple days of recurring meetings per client and then deleting all the days I don't need which creates another problem. Thanks

No matter what I do, my settings keep reverting to a blurred virtual background as the default for meetings. So every time I start a meeting my background is blurred.

I can set virtual background to "None" (or anything else) during a meeting, and even in settings, but upon going into a new meeting it STILL reverts to blurred.

It happens using the same Zoom account on other devices (PC/Windows, Mac, and iOS), but if I use a different Zoom account on the same devices they work fine (i.e. no virtual background). 

I KNOW the issue is specific to my main Zoom account and not the devices or Zoom clients on each.
