>Description:
I have several powerpc macs with similar symptoms. Audio plays out on the system but it's way slower than it should be. The load on the system is nominal (3% load?)

My test has been a uncompressed wave file of kiasmos - looped & an mp3 file. I've played both with mplayer & the wave file with the tool in base which the name now escapes me.
in both scenarios the files are pitches down way lower than they should be.
>How-To-Repeat:
Play an mp3 or wave file on a powerpc mac

 What audio chip(s) are you using? I just tried mpg123 on my iBook G4
 ( with snapper/tas3004 audio ) and Mini2 ( aoa codec ) didn't notice
 anything wrong. I'll check awacs in a little bit.
 Both -current from a few hours ago.

 TAS3004 on a PowerBook6,4
 TAS3004 on a PowerBook5,2
 TAS3001 on a PowerMac4,5
 snapper? on a PowerMac10,1

 Wave file I'm testing
 RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16 bit, stereo
 44100 Hz

 I noticed that that microphone is active when playing audio back which
 results in feedback once the volumes gets beyond a certain point.

 I know the audio is slow because playing the same file back on QuickTime
 7, with say the PowerBook6,4 on Tiger, music is back at the expected speed.

 Hello,

 Odd, I tried a PowerBook6,3 which should be identical in terms of audio
 hardware and there was no such thing.
 Just to be sure - could you try mpg123 from recent pkgsrc?

 Hmm, I wonder if audioplay gets something wrong with LE .wav...

 Huh, I haven't seen ( I mean heard ) that one either.

 Sounds the same here as it does on a sparcstation with dbri audio.
 ( that was the closest thing I had which isn't a mac... )

 have fun

 Turn up the volume using the function keys on the keyboard.

 Will give an up to date version of mpeg123 a try.

 mpg123 wont play the wave file but I tested it with an mp3 file. Same result=
 . Pitch is lower than it should be.

 Doesn't appear to be specifc to audioplay=20

 :)
 Sent video of the pitch issue and audio playback on tiger & netbsd from the s=
 ame system off list.

Fix commited

From Nat:
it seems that snapper_init should be called before audio_attach_mi, as snapper 
init is setting the rate to 44100 after the hardware format has been configured 
by audio_attach_mi.

audio_attach_mi should be the last thing called during an attach of an audio 
device so the audio device is ready to be configured when audio_attach_mi is 
called.

 Explains why I couldn't reproduce it - my mp3s are all 44.1kHz.
