AAE -9173 Issues

[Forza]

Hey guys, I was discussing this issue on the UAD forums. I'm not seeing the issue like you are. The few times I was seeing it, I was able to resolve it by forcing a session (and core audio) restart by changing the playback device to PT Aggregate I/O, and then back to my primary interface. Seems like it might be a driver and or buffer issue.

The theory would substantiate why offline bounce would work and real-time won't. I don't believe offline bounces actually go back to the interface.

I'm reading that some of you are also doing a system restart to resolve the issue. This would also clear any clogged driver buffer out. Try the playback engine toggle and see if that doesn't work to, might save you some time.

When I say "often" on large sessions, I mean playback stopping with that error every 30-90 seconds. 40% CPU.

I do see a spike when it occurs.

-->after the error 100% of the time I have to change the buffer (doesn't matter if it's reduced or increased) or I have garbled, bit-crushed audio on playback.<--

Mac Pro Dual Processor 4,1 and 5,1.
10.8.4 and 10.8.5 both exhibit on both systems.
Both systems have PT10.3.7 co-installed.
Have tried multiple interfaces, driver versions, brands, even onboard audio.
Systems do NOT have the same plugins installed.
Systems both have UAD-2 cards.
Have tried SSD and spindle drives.
Have tried increasing/decreasing the RAM allocation.
Systems are optimized to AVID specs.

Happens during RTBTD on 100% of projects.
Can happen during playback on single track projects with no plugins.

Start/Stop of the transport (especially stopping playback, then immediately restarting) aggravates it.

Really appears to be buffer related, but session will run just as well/poorly at 128 as it does at 1024.

You actually only need to change the buffer size to clear the error.

Restarting doesn't do squat. Changing buffer sizes doesn't do it either. Or delay compensation. Avid told me that resolution would come from a future update. Obviously not 11.2.2. Real Time bounce works in 11.1.3 but not in 11.2 and after. Real Time bounce can work at some resolutions, perhaps the ones some people work in, but at 24/96 bounces consistently break with the -9173 error. I get this in both 10.8.5 and 10.9.5 (Mavericks was a fresh install from scratch as well as fresh installs of PT and all plugs). ProTools is broken.

Sorry, no, NOTHING makes RTBTD work. I meant when it happens on playback and the audio goes to crap.

-->can anyone confirm these errors are occurring using HDN?

-->is it happening to users with ONLY 11 installed?

I had gathered that it wasn't affecting HDN users or users with only 11 installed from some of the other threads, but I may be wrong.

[CygnusX-1Bk2]

I had gotten it during playback with 11.2 but not 11.2.1. I am running HDN and I know that the Bounce error is happening on HDX systems as well. Seems like Mac Pro 4,1 and 5,1 are affected. Not all, apparently but well more than enough to be serious.

[propower]

Don't know if this helps but -- All 96kHz - buffer between 64 and 128
nMP 10.9.4 11.2.1 HD Native TB
No install of PT10 ever on this system

I don't do RTBTD usually but In the couple of experiments (trying to help) on RTBTD I have had zero occurrences
In normal playback and record (small sessions) zero occurrences
Have actually never seen this on this system.

[Matt Hepworth]

Retina MBP is also affected.

One thing that might be worth noting about this -9173 / real time bounce issue. I never saw this issue until recently (this is spearate from regular -9173 and -9093 errors during playback due to weird VI problems which I do get). But being on 11.2.x for several months I never had the problem and felt like one of the lucky ones. However - it just came up for the first time a couple days ago. I had recently installed a demo of Slate VTM and that might have started the issue. Specifically - I was bouncing a song and had a few plugins on the master track including VTM, followed by Waves L3 last in the chain. Did a real time bounce, no problem. Then, when I deactivated the L3 (but still left on the master channel) to do a "non-mastered" version, I got the -9173 error every time during a real-time bounce. I tried about 5 times, even restarting pro tools after a couple, then gave up and did an offline bounce which worked fine. I haven't done any further testing, but I wanted to share this as I've never had this issue before now.

I'm just glad to know that it seems to be on the radar of Avid's debuggers. And hoping that it is fixed a)very soon, and b) NOT as part of an update that you have to be on a support plan to receive.
