I've just been having a quick play with Jitsi v166 on a Hisense Sero 7
Pro Android Tablet connecting to v2.3.4900 on my Windows 7 PC and the
audio quality from Windows to Android was OK but in the other
direction it was very bad and choppy and not good enough for real use
I tried disabling the Opus 48000 codec on the Android to see if a
lower quality one would work better but no difference. Both devices
are connected to my home network, the PC is wired whilst the tablet is
wireless and both were using ch3kr.net XMPP accounts.
