Failure setting up channels
The call to snd_pcm_hw_params_set_channels in do_connect_pcm may fail, it should probably be replaced by one of it's alternatives, or at least just not abort if it fails.
It does for me
[apulse] [error] do_connect_pcm, snd_pcm_hw_params_set_channels, Invalid argument
with Telegram Desktop
All calls could fail.
In case of snd_pcm_hw_params_set_channels() failing, I don't know what to do. In that case application requested a particular number of channels (1 or 2 usually), but audiodriver said it can't provide that. Should apulse convert/split/mix data in that case?
Also, is this dmix-enabled device? I think, ALSA's plugins should handle format convertions by default.
@sovietspaceship Install alsacap and check with alsacap -d default that the device is configured properly.
You'll probably need to use plug:dmix (playback) and plug:dsnoop (recording) unless you have a high-end card.
You should get something like this:
$ alsacap -d default

I'm already using dmix and dsnoop; alsacap -d default outputs

Latest version of Telegram segfaults running under apulse. I opened an issue on their repo because it's probably their fault.
Latest version of Telegram segfaults running under apulse.
This is very similar to #43, which was kind of fixed. Also, latest Telegram app seems to be working through apulse just fine. It uses some not implemented functions, but plays audio anyway.
