}Additional player setup steps
In our HLS stream https://foliovision.com/hls/master.m3u8, both video and audio streams use the same HLS AES-128 decryption key, on the same URL.
This has worked fine for a long time, then starting with HLS.js 1.6.11 it would load the decryption key separately for video and audio, reported here (no need to read, only adding link for reference): #3900 (comment)
We are happy to see that HLS.js 1.7.0 is loading the decryption key only once again.
But it seems to run into this strange playback issue.
The point is that since Safari playing HLS stream natively only load the descryption key once, so should HLS.js.
So to sum it up:
More details in test steps below.

Configuration
Additional player setup steps
In our HLS stream https://foliovision.com/hls/master.m3u8, both video and audio streams use the same HLS AES-128 decryption key, on the same URL.
This has worked fine for a long time, then starting with HLS.js 1.6.11 it would load the decryption key separately for video and audio, reported here (no need to read, only adding link for reference): #3900 (comment)
We are happy to see that HLS.js 1.7.0 is loading the decryption key only once again.
But it seems to run into this strange playback issue.
The point is that since Safari playing HLS stream natively only load the descryption key once, so should HLS.js.
So to sum it up:
More details in test steps below.
