9.12 and 2408mk3 Drops Out

[labman]

If I am understand the issue you are listing, I have seen that many times with 9.12 on big PCI rigs with HD192 and 2408mk3. Out of nowhere, DP will just cease to play audio until we,

1. visit hardware setup and toggle clock or buffer. Dont need to change it, just toggle it.
2. quit DP and replace with our saved clean prefs.

And as you say, all other apps keep passing along audio just fine. DP9.02 does not do this. So it is very much a DP 9.12 settings getting corrupted or something like this, as the other apps are using the same driver.

I appreciate the info you are providing.

Interesting that your HD192 is having the problem too. So it's not just a 2408mk3 issue. Labman, if you haven't done so please submit a TechNote to MOTU so they know it's an actual issue and not just me and cody. I'd love for them to address this issue in an update.

MOTU also suggests trashing the prefs. I have a set of saved prefs, but since the problem has been with me since day one of installing 9.1 I can't be sure that will do the trick (a corruption that effects 9.12 and not 9.02 seems possible). Plus I've made a ton of changes since I saved them and it's a huge PIA to get them all back.

And, yes toggling the hardware fixes the issue overtime, but that's exactly what I'm trying to avoid. On big projects it can take quite awhile.

Thx!

[labman]

You are absolutely correct that the toggles are a pain. Takes forever for it to reload if you have a lot of V.I's and tracks and send out to VEP slaves.

I actually discussed this in detail with one of the senior techs 4 weeks ago. They logged it and were gonna discuss.

No resolution to this yet on my end, but another bit of info:

I noticed that live instruments playing while in Direct Hardware Play-through mode continue to pass through the 2408mk3 when this issue occurs. You can even toggle them on and off when you Record enable tracks in DP. Not sure what that tells us, but at least we know there's still some level of communication between DP and the i/o when this happens.

In case anyone is interested, this is still an issue in 9.13. DP continues to lose connection to the 2408mk3 intermittently on largish projects or any project that tends to spike.

That is NOT good news. MOTU has known about this for many many months. Told them back early on with DP9. Maybe there is a driver coming. sigh...

It is a bummer! But it looks like there's about three users with issue - or very few anyway. That and the fact that they've never been able to replicate the problem (so i don't think they could create a driver fix), I think it's unlikely MOTU'll ever make it a priority. Sadly, I think we're kinda on our own with legacy-hardware.

There's likely plenty of MP 424 users that aren't having the issue. I wonder what the diff is between their systems and ours. Labman, do both your Mac Pros have the issue? Above you say

Since it occurs on both i/os, could it be bad 424s? Swapping 424s would be an interesting experiment.

Just an update on my end. I went to Sierra and 9.12 and so far have been good...

Considering 9.13 now...

Yup all rigs have the issues, but ONLY with DP 9 and above.8 dead on clean. \ Only happens here every few days. Just bummer though.

Could App Nap be the problem? If you haven't disabled it, try and see what happened.

Dunno. I saw that this morning and turned it off (who knew?!). So far so good, but I often go days without it happening depending on the project. ...Labman, may be able to get a faster verdict since he has multiple machines with this issue.

I've been experiencing this same problem w9.1.2 and now still with 9.1.3. I've got 3 2408mk3 and a 24 I/O on a PCI-424 in a 12-core MacPro tower. The workaround when this happens is to go into 'Configure Hardware' panel and just click 'OK'. Sound comes right back. The issue is not limited to a single channel as the Hardware plugs stop sending audio also. 9.1.2/3 seeming to be a massive nightmare for my system. Timing issues, crashing issues and this PITA BUG. I'm a programmer. Even if it's happening to only one user... It's a bug. Granted a hard bug to track down, but a bug just the same.

[labman]

App nap is off here. And has been.

Guitardoods workaround is what we do. Open config hardware and OK. Always works.

But stupid.

[dix]

The workaround is often not practical for me. I tend to work with large MIDI projects so toggling the hardware config can take quite awhile when you're in the middle of trying to compose something. I just go back to 9.02 after it happens a couple times.

The club of MN users who have this issue remains at 3 now that cody seems to be sorted by updating his OS to Sierra (weird that would fix this, but okay). Amplidood, what OS are you running? ...updating to Sierra brings another level of complication. I'm not sure I want to do it just yet unless I was relatively certain it would fix this issue.

oh yeah Dix. 100% agreed. workaround is Total stupid buzzkill
