Description

stdout (using UNIAUD-Plugnin) says:

...
sr: 11024
channels: 1
sample rate supported: 8000 to 48000
rate refine err: -22, 11024, 2, 2, 2
pcm open error -10006
Buffer: 0
Output bit per sec: 11024
Error in audio init

...

I only get sound out of the speakers when using DART - plugin
WAVE - plugin also works. Allthough I get sound, the speed is wrong,
Audio is played too slow (both DART and WAVE output)

Using uniaud-plugin no sound at all.

When I selcect 'Resample everything to 48kHz' I get sound,
but it's only intermittent noise.

what version of uniaud.dll?

comment:2 Changed 18 years ago by fbakan@…

latest version from uniaud114rc1

comment:3 Changed 18 years ago by vladest

looks like your audio card doesnt likes 11024 Hz sample rate instead of standard 11025 Hz

I don't believe that it's a problem with the audio-card (Crystal-Chip), tried a different computer with C-Media, same problem.

I just found some short clips with 11024Hz sample-rate on the WEB you could try yourself:

(FFPlay latest version compiled by Paul Smedley based on FFMPEG) plays these files fine including audio.

attached.

more info: I was wrong, also ffplay does not play the movie correctly, it's a little bit too slow.

If I recompile plugins/uniplug.c for testing and replace SamplingRate? in line 194 with 11025, wvgui plays the little avi, but with minor interruptions of the movie and sync-problems.
