Clocking Problem With Echo Layla24 + Osx, a basic clocking error- HW OR SW? Options

[tobes]

greetings,

just before i send my Layla24 back to Echo (on their advice) ....

Has anybody had trouble playing ANYTHING back at correct speed thru the Layla?
(OSX 10.2.8 + Layla with 1.3 driver + i-tunes.)

I've tried every setting i can find on the Layla and in the Audio/Midi Window, but CDs/Logic files always play back too slow.

If any Layla users have have this problem.. please shout..

regards

You don't have a sample rate problem here do you?
If you had a poor clock I would expect clicks, pops etc during playback. If you were playing a 48k file at 44.1 then it would play slow...

hey
Its not as if I'm hearing clicks/pops in otherwise normal playback.. there is just no correct playback rate at all!

From what I can tell:
- the Layla console has no sample rate menu of its own
- the only clock-setting menu is 'Input Clock', and on mine this is set to "Internal" with the other options (SPDIF, WORD, ADAT) blanked out.

In the OSX Audio/MIDI window, there are nine sample rate options:
8000.0Hz, 11025, 16000, 22050, 32000, 44100, 48000, 88200, and 96000Hz (all followed by "32-bit")

None of these rates, 44100 included, will allow playbabck of a CD at correct speed. (CDs always 44.1khz right?)
As I explained to the Echo guy, there just don't seem to be any other parameters I can change.

have you got a word clock or spdif source you can try?
Don't forget, spdif is just unbalanced AES so you can get spdif from an AES source by unbalancing the lead.

If all sounds good this way then you could have a driver issue but it's not a definitive test.

You need to find an ideal core audio / mac os / echo24 setup as the driver won't have been updated since early Jaguar, maybe an earlier core audio or earlier jaguar will help.

Have you got any other pci cards installed? Are there any user groups etc?
