[Bug] where did disappear low-bitrate audios?

[ifsdk]

I suspect this is not a bug but a youtube's fault as I see that in other frontends too. With my very slow internet connection I'm disappointed that in some point in time audio bitrates like 30k have disappeared and now there are lowest ones like 50-60k.
What did happen exactly?

It's because we had to change the client used to fetch the video data. Before we were using the Android client, which provides low bitrate audio. But now we're using other clients who don't. That's not something that we can fix for now, sorry.
