Sound is too fast. Zelda Classic Debian Wheezy

[aaronvaldes]

I am testig out the latest release.
The sound sounds way too fast.
Can someone help?

I love this game.

Do you use ALSA or PulseAudio?

[aaronvaldes]

PulseAudio

I installed ALSA drivers.

I have tried with both and no difference.

How can I make sure that Zelda Classic is using correct driver?

Which is correct? ALSA or Pulseaudio

Perhaps I need to configure Allegro to use the correct driver?

[Chris Miller]

Well, I looked into it. The only thing I can think of, is use OSS.
Here's the thread I found. It's for Arch, but the principle's the same.

[aaronvaldes]

I don't understand.
I tried it in full screen and it speeds up the sound.
Changing resolution and it fixes it and then it happens again.
Not stable at all.
Why would changing resolution have anything to do with sound?

[Chris Miller]

I'll try and do some more digging, but I do have a theory. ZC is most likely running at a very high priority, same as it does in Windows 7(strangely, XP escapes this problem). That can cause some weird stuff, and maybe even interfere with your sound. It's kind of hit-or-miss, mostly depending on what kind of hardware your system has. You might try running ZC, then switching back to the desktop while it's still running. Then open your task manager and see if you can set the priority to normal.

I checked and PulseAudio and Zelda are definatley running.

There nice values seem normal.

I tried turning them down to -20 for lowest priority and still no change.

[aaronvaldes]

I checked TOP

pulse audio is at about 1.4 percent CPU usage when working ok.

When it is not ok pulse audio is at 20 percent cpu usage?

What would cause pulse audio to think it had to do so much work?


Just Tested:

I was playing and then when I picked up a fairy, Pulseaudio went to 20 percent and sound went super fast again.

[aaronvaldes]

./zelda-l -v0

I ran zelda with the v sync off.
And now it seems that the fast speed is matching the speed of the game.
Totally not playable.

I'm not familiar with the linux builds but I believe @Saffith was working on a similar issue a while back. Hopefully he can shed some light on this for you.
