Prior to iOS 14.7, our tracks with PCMU and PCMA audio worked fine. As of 14.7 we're finding that PCMU/A audio will not play correctly on iPhone or iPad. In most cases playback never begins, in some cases playback will start and then stop after about half a second. In the same test case changing only the audio codec to Opus, audio plays as expected every time.
FWIW, I've also found that backgrounding the browser app and then bringing it out of background will result in another fraction of a second of audio playback, then stops again.
Hi Jay, I'll check this further tonight. Can you confirm whether https://webrtc.github.io/samples/src/content/peerconnection/audio/ is working or not for you? If you have MacOS, can you repro the issue there as well?

Thanks Youenn. I can confirm that https://webrtc.github.io/samples/src/content/peerconnection/audio/ is working as expected for me on the same device that exhibits problems with my source. Unfortunately I am not equipped to test MAcOS. I will set up a test case with my problem source (wowza streaming engine) and send info to you offlist a bit later today.
