I'm experimenting with Jitsi and had a number of problems, mostly with
sound. More on those in some other mail.
One of the problems is current. It's happening with Jitsi 2.2 on Linux
Mint Debian Edition, with PulseAudio as backend. It seems that when a
new voice call is started, the system mic level is set to maximum. I
can't tell whether this is done by jitsi or PulseAudio. Does anyone
have any experience with that?
Why is this problematic? This machine uses some Intel HD chip, as
do many other laptops. They have something called 'Internal Mic Boost',
which is accessible through for example alsamixer. If this stuff is
enabled, it causes ridiculous levels of noise, there isn't even any
noticeable amplification of the mic sound. On the machine mentioned
above PulseAudio enables this stuff if the mic level is set any higher
than 25 percent, and thus causing havoc.
It's clear to me that PulseAudio is stupid, but that's nothing new.
What I wonder is whether it's PulseAudio or Jitsi that puts the level
to 100% whenever there's a new call.
