playback stalling due to empty audio buffer [only firefox]

[shoys89]

Hi,

We found out that in Firefox for certain dash assets the audio buffer is not being loaded no data is appended.
The following log [audio] Switch to index 0; buffer is empty keeps on indefinitely, while the video buffer loads fine. As a result the player stalls and playback never starts.

Is there any reason why the audio buffer could not be created, and if so is there any way for dashjs to tell what the reason for this was, it seems that dashjs does not catch this properly?

Any help is appreciated,
thanks.
