Output of loading skype with "PULSE_LATENCY_MSEC=30"

Arch Linux recently removed the use of PULSE_LATENCY_MSEC=30 when running Skype. I now get no audio in Skype. This includes notification sounds like the startup sound.

Running Pulseaudio 5.0 on 64bit Arch Linux also with a 32bit libpulse.

I have attached two logs of pulseaudio -vvvvv. One with PULSE_LATENCY_MSEC=30 and one without. The log without PULSE_LATENCY_MSEC=30 has many repeated lines of "D: [alsa-sink-ALC887-VD Analog] memblock.c: Pool full", which looks suspicious.

Just to be clear, the sound only works when PULSE_LATENCY_MSEC=30 is used. All other programs' sound appears to work fine on my PC.

As far as I know, this is some weird Skype bug, so I'm closing this with resolution NOTOURBUG.

I don't know why Arch removed the workaround.

They removed it because the "workaround" didn't work for everyone.

Some people have a working Skype with PULSE_LATENCY_MSEC=30 and broken without it.

Other pople have a working Skype without PULSE_LATENCY_MSEC=30 and broken with it.

Having such a workaround in the repo is dumb.
