Steps to reproduce

1. Go to https://hlsjs.video-dev.org/demo/?src=https%3A%2F%2Fqcdn.screen9.com%2Fmedia%2Fm%2FH%2FmHZBquU3eCmLzwO3vXq0Vg_auto_hls.ssl.m3u8%3Fauth%3DPGeCUq3_tpmkQlOOdC3ALUPdIvQ21OPGUDvSbUe2jOyHo1jn2fTXw0vOyynaj02hYzdamtkti3LZt69sXFpjjw&demoConfig=eyJlbmFibGVTdHJlYW1pbmciOnRydWUsImF1dG9SZWNvdmVyRXJyb3IiOnRydWUsInN0b3BPblN0YWxsIjpmYWxzZSwiZHVtcGZNUDQiOmZhbHNlLCJsZXZlbENhcHBpbmciOi0xLCJsaW1pdE1ldHJpY3MiOi0xfQ==
2. Start the video and enable sound if it is muted. You should hear the default audio track without audio description.
3. Go to the Audio Tracks tab and switch the audio track to the second one in the list. This track should include audio description. The narrator's voice should play from the 1st to the 13th second.
4. Then, switch the audio track back to the first one (without audio description) and rewind the playback to the first second to listen to the track.

Expected behaviour

Throughout the entire length of the video, you should hear the original audio track without any narrator comments from the audio description.

What actually happened?

When the audio track is switched to the audio description track between 0-5 seconds of the video, then after switching back to the original track and replaying the video from the beginning, you will hear the narrator's voice from the audio description track until the 5th second. After the 5th second, the correct original audio track will play.

If the switch to the audio description track occurs between 5-10 seconds, then after switching back to the original track, you will hear the original track from 0 to 5 seconds and from 10 seconds to the end of the video. However, between 5-10 seconds, the narrator's voice from the audio description track will still play.

In general, strange behavior occurs when switching between audio tracks multiple times. I tested this video on other players, and audio track switching worked without issues, so I believe this is unlikely to be a problem with the HLS playlist itself but who knows...

I would appreciate any suggestions and would be happy to provide additional information if needed.

Console output

Console output looks normal except for this warning that sometimes occurs: 
`transmuxer-interface.ts:394 [warn] > MPEG-TS PMT found at 5828 after unknown PID '256'. Backtracking to sync byte @0 to parse all TS packets.`
