Summary Safari not calling external audio
Renee
Reported 2023-04-09 17:31:15 PDT
When running broadcasting stream using webRTC in Safari, the external Audio Device will not broadcast audio. To reproduce: In Safari 16.4 on webRTC when audio input is changed to external audio sources - (getUserMedia) is not getting the stream. What we tried: Google Meet WebRTC initially did not recognise the stream when audio input changed, however after 30 seconds the audio is recognised, albeit delayed. Audio syncs at the 1 minute mark. Same device tested in Chrome without issue. Devices: MacBook M1 Pro Ventura 13.3 Safari 16.4 External device: Canon XA20 for Video/Audio connected via Yuan PD570 Pro Capture HDMI - A/V to USB capture device https://www.yuan.com.tw/products/capture/external/pd570_pro_hdmi.htm

I do not have access to the device. Would you be able to reproduce the issue and generate a sysdiagnose shortly after the reproduction of the issue. Then send it to me (youenn@apple.com) with the timestamp of the issue? Is the same setup working in Chrome and/or Firefox?
