**Current behavior:**
Unable to use iOS devices to play sound - there appears to be an issue with HLS streaming

**Expected behavior:**
Sounds should play - 
We were able to play sounds in UV version 4.0.19
**Steps to reproduce:**
Using any iOS device go to this URL, making sure that you are using uv4.0.22: 
https://access-beta.bl.uk/item/viewer/ark:/81055/vdc_100133103553.0x000002
Error message appears saying no media selected

Hello @LlGC-szw, As we briefly discussed on the 28/9 call, I guess from the BL point of view it would be good to have an indication when this issue is likely to be merged to the next UV4 community release. Many thanks.

Flagged to be discussed in the Steering Group.

We think if IIIF-Commons/iiif-av-component#92 is released and included in UV it will fix this issue.

Have just published v4.0.24 including this fix
