Bug: Reproducible audio issue on iPhone 15 and iOS 18

[rvalessandro]

Expected behavior

Audio and video call to work.

Describe the bug (unexpected behavior)

Two way video call - both parties can see each other, but only one person can hear the other party.

Seems to be the case that it's device / OS specific. To elaborate further:

1. Mac v mac : Ok
2. iPhone 12 v iPhone 12 : Ok
3. Mac v iPhone 15 : iPhone 15 unable to hear audio
4. iPhone 12 v iPhone 15 : iPhone 15 unable to hear audio
5. iPhone 12 v mac : Ok

For items with iPhone 15, we tried it using both iPhone 15 and iPhone 15 Pro.
Both running iOS 18, details below.

System information

Devices used:

• Macbook pro: Apple M1 Pro
• iPhone 15: iOS 18.0
• iPhone 15 Pro: iOs 18.1 beta
• iPhone 12: iOS 17.7

Additional context

We're doing a 2 way video call with daily private room.
It seems to be working fine until 2 days ago, 9/29 but it's not working since yesterday 9/30.

Hi! Thank you for the report, I have not been able to reproduce this issue and have not heard of others getting this. Can you tell me more about your setup? What browsers are you using on each device? Are you using prebuilt embedded or is your application custom/callObject? When you get the issue, which person is unable to hear the other one? Is it always the person on mobile or does it change?

If you continue to have trouble, could you reach out to help@daily.co and reference me and this issue and provide a session id where the issue has occurred?

Thanks!
