Firefox on Android audio gain too low

[hamez99]

Hi!
I'm using RecordRTC in a site i'm building to capture videos and experiencing an issue where Firefox on android records the audio too low. In Chrome on the same device it sounds fine, but it's like Firefox has a severely reduced gain. Is anyone else experiencing this? I'm not able to find anything else online about this and I've dug through the APIs for both RecordRTC and WebRTC to see if there's something I need to change for firefox, but nothing I've tried seems to work.
However Firefox on windows records perfectly.
I dont think this is necessarily an issue with RecordRTC since it seems consistent with other WebRTC demos, but I'm at least wondering if this has been encountered by anyone else or if there's a known fix (or a known issue with Mozilla - i couldnt find that either).
I'm using a Samsung S6 edge that has Android 7.0 on it if that makes a difference.
Thanks!

After more digging, it seems i can get slightly better gain from the RecordRTC demos than my own implementation. However it's still an order of magnitude lower than chrome.

I also discovered through testing that firefox seems to be pulling from the "headset" microphone instead of the "speakerphone" microphone. It appears that firefox can only detect the one because i'm not getting any other options.

I have a very similar problem on my Samsung Galaxy S8 with Android 8.0.0.
I'm trying to register an audio through getUserMedia and while the audio seems to register correctly, if I try to listen to the recording again all I get is something almost inaudible.
