has anyone seen random busses/outputs stop working

[Leopard1]

Frank, you're experience is not heartening. All of the re-building, deleting, duplicating, clean installs and such don't seem to work long(either seconds or as long as a day or so). This latest session takes hours just to rebuild io's and tracks-- it is truly massive. PT8.03, PT 7.4.2, on multiple systems(at least 4). The problem doesn't seem to be exclusively with HD3 users, either. But the problem persists with less options for truly large sessions. A robust PT user should get love too, no?

The digi guys seem to be working on this problem as we speak with some earnestness. I've seen post on this issue since '05. Maybe this will be the time to silence this disappearing bus issue once and for all?

Leopard1,

like I said, IMO it is not necessary to re-build the i/o setup (truely a PITA). de- and re-activating a given bus or ouput seems to fix it temporarily.

The nasty thing about this is that with 50 tracks of atmos plus dialog running there is no way you can possibly hear and find this bugger quickly. You might have made a great mix and then you hand the session to an assistant who does the play-out and he won´t even notice that the surrounds are coming out the center right away. It will just sound somehow different. Then you start tweaking levels for an hour only to realize that PT was playing back entirely wrong in the first place.

It´s truely a scary bug.

Probably one of my top 2 PITA-bugs in PT. The other one is the bug that wont let PT pull automation along the clips but that´s in another thread.

I just had this problem on a large session in PT 8 on an HD|6. De- and re- did not work, the entire left side would not play. I had to delete the main bus and create a new one. I also purged the DSP cache. Then I was able to work.

This bug ain't fixed yet!

By chance are you importing old IO setups? I recently had these problems on 7.4 and found that re-building the IO from scratch helped. I realised that my IO setup was based around something that's been with me since PT 6 and subsequently modified many times.

[Frank Kruse]

Yes Ray, this does help. Question is why and when does the I/O get screwed and how this can be prevented.

[garnoil]

yes, I had that problem too!

I've also had this happening for years. It's usually with big sessions using almost all the busses. I'm currently on v 7.3.1.

I had rebuilt my template from the ground up, thinking maybe there was some corruption, but this did not stop it from happening.

I originally thought Waves plug-ins were the culprit, because de-activating and re-activating them would sometimes allow audio to pass. I now think that is a separate Waves issue.

I found that going into the I/O and dragging the path assignment to a new bus usually works (but only if you have a free bus to drag it to, of course).

Now I just close and re-open the session and that seems to always work.

It's disconcerting when you realize you don't have your subtle FX playing during a layback. It keeps us on our toes!

Has anyone experiencing these problems looked into reseating their cards and TDM ribbon cable? Just a thought...

I have experienced every issue discussed here but I have ONLY seen it after a DSP reshuffle is required (adding another plugin or panner, or a new track). Are you all saying this happens RANDOMLY? Honestly, I've had it for years and years, too, but ALWAYS after a reshuffle. Closing and reopening the session has been my fix but I've honestly never tried to deactivate/reactivate the busses involved.

[CCash]

For me it is totally random.

I open a session that is usually fine, hit play, and a bus (or busses) is "asleep". I close the session and re-open it and it's awake again.

I have not tried re-seating the cards -- might not be a bad idea. And for the record I use an expansion chassis.
