Motu traveller mk1 - no audio at high bitrates

[bleep]

Hi, I have recently purchased a second hand traveller mk1 which I have running on a MacBook via an adapter chain (ending with Thunderbolt 3) (macOS Monterey).

It works fine on 44.1 hz, but when I bump the resolution up to the higher values, the audio just cuts out.

I’m using the drivers listed for the traveller mk3. And have the settings on the machine set to defaults.

This is my first pro grade audio interface, so I have minimal knowledge about this kind of machine.

I’m not sure what’s causing the problem. Could anyone advise?

Cheers

Not quite enough info to even begin guessing.

What is your MacOS? What is the desired sample rate and how are you setting it? If from your DAW, what is it?

Searching for Sample in the manual shows 197 listings.

Thanks for your reply and the link. I’ll give it a read.

It’s a head scratcher this one. I was hoping that it was a common problem and people knew about it.

It’s macOS12 Monterey. And I’m selecting the bitrate in the Motu setup app in macOS. It’ll work for 44.1, 48 kHz (maybe one higher) and then the audio will cut when I go higher than that. (And won’t work again till I restart the computer and the sound card). The lights on the front panel of the unit do show the change when it’s triggered.

Ideally I’d like to be able to choose whichever high res bitrate I wish.

Is it possible that there’s a hardware fault?

Could it be that the software on the system crashes the card because system apps and google chrome will not provide bitrates this high?

And I’m using Ableton Live.

Your answer isn’t quite as complete as I would have liked but start with the manual. Searchable PDFs are your friend right now.

If you’ve not reset the unit to factory default yourself, do that first—don’t take someone else’s word that it was done.

You are using external power, yes? The FW bus power spec is 24–27V and one of the Apple adapters passes only 7V.

From Sound on Sound:

The Traveler can be powered solely by the Firewire connection to the host computer, but only if a six-pin Firewire connector is used at the computer end — miniature four-pin connectors won't work.

48k is the standard for most these days, broadcast included.

Just sayin'.

Hi there! External power, check. Factory defaults, check.

I’ll do some more experimenting with it, cheers

For the record; I don’t feel too hard done by with this. Just looking to try the higher bitrates if I can.

After a sleep, I’ve managed to find a way to get the high res settings to work.

Word Out needs to be set to system clock, and restart the system. Then it seems to work without troubles.
