SPU2-X, PortAudio ALSA output mutes itself at random

[OrdinaryMagician]

I'm on Arch Linux x64. PCSX2 built from latest commit as of writing this.

It seems that when using ALSA output with PortAudio, sound will just mute itself until I reload the plugin, sometimes almost immediately, other times after less than a minute. What I find strange is that there is nothing in the log, nothing in stdout/stderr, it just happens without any warnings or errors.

If it's relevant, I have integrated Intel HD Audio and here's my asound.conf, which may or may not have any impact on this.

Try SDL output.

[OrdinaryMagician]

SDL output works perfectly fine, at least for SDL 1.2. With SDL2 I get choppy sound.

[gregory38]

I just fixed SDL2 normally. PortAudio doesn't support pulseaudio which is now the linux standard. It could be related.

[OrdinaryMagician]

I don't even use pulseaudio or have it installed anyway, but I guess I'll switch to SDL2 now.

Hello, I'm seeing the same issue on my end, even after upgrading to the latest PPA dated yesterday with SDL2 fixes. Gregory, I've posted my SPU2-X config here for reference as you requested, hope it helps.

I found other bug report with the same issue on others applications.
For me the issue is related to bad interaction of portaudio and pulseaudio. SDL is the alternative.
