PulseAudio - sound skipping - suggest increasing buffer size
0%
Description
Games music giving almost imperceptible sound skipping, probably need more buffer.
It sounds much better to change the code in this way in pulseaudio plugin:
void PulseAudio::SoundLoop()
{
if (!PulseInit()) {
thread_data = 2;
return;
}
while (!thread_data)
{
int err;
//int frames_to_deliver = 512;
int frames_to_deliver = 768;
m_mixer->Mix(reinterpret_cast<short *>(mix_buffer), frames_to_deliver);
if (pa_simple_write(handle, mix_buffer, frames_to_deliver * 2 * 2, &err) < 0)
{
ERROR_LOG(AUDIO, "pa_simple_write fail: %s", pa_strerror(err));
}
}
PulseShutdown();
thread_data = 2;
}

Could we make to increase or decrease the buffer as an option in the plugin? This way each person can adjust.

That would be amazing, since the latest buffer size changes they made on the hle dsp turned the audio of many games into crackling crap audio... no offense...
If we could set the best config for ourselver that would be nice...

And i'm not refering only to this Pulseaudio... I use windows... so Dsound is my point...

frango, which revision are you referring to?
Updated by nakeee about 14 years ago
why not just make the buffer big enough for everyone to be happy?
Updated by darumo about 14 years ago
large buffer is more delay, the value should be as low as possible to sound right, but now is too low and sounds bad in my Audigy2, so said it would be good that the user could change this in the options.
(is translated with Google, complaints of bad writing to them xD)

Is this issue relevant after r020ab743a90c165e836d4bb3cce57cb60443ad7e?

I have problems in some videos and music (very large slowdown and skipping), but no problems in sound effects. If I use Alsa these problems do not exist in those games.
Metroid M (R3OP01)
Onechanbara (RONPG9)
Punch-Out! (R7PP01)
I wanted to have tested the game Muramasa (RSFP99) but seems to work now (I did before disabling function "progressive image" but that option does not exist or do not see) and maybe the NTSC version has the same problem.
Separate problem is that I had to add the ISOs folder manually. (add my Home folder not the selected folder)

Muramasa NTSC so I could try and it works well. (the PAL does not currently work in the emulator for what I see)
Besides the problem when it occurs slows the emulator, but the emulator says it goes to 100% speed ...
Doing more testing I realized that the problem is not present with LLE, the problem only occurs in HLE mode. The problem is when you combine HLE and pulseaudio.

@ darumo
Thanks, does changing BUFFER_SAMPLES from 512 to 768 alleviate the issue again?
Updated by darumo over 11 years ago
I'm sorry, I've been telling problems and everything came through remnants of old versions compilations. (When I deleted everything and rebuilt from zero everything worked)
Everything works perfectly ... Sorry for the inconvenience. And the old problem of buffer you have it solved, no need to increase it.
