BSODs after sample rate change - Hapi and Ravenna ASIO

[archive]

I seem to be encountering a fairly consistent and repeatable BSOD scenario:

- use Hapi and Ravenna ASIO driver at 96k with Pyramix

- close Pyramix, switch Hapi to 44.1k

- open another program that calls the Ravenna ASIO driver at 44.1k (in my case both Samplitude and Sonoris DDP Creator do this), and bam, BSOD. Every time.

After rebooting I can then open the program (either Samplitude or DDP Creator) and proceed as normal. Anyone else seeing a similar crash, or have any thoughts on solutions?

I have the latest Hapi firmware and drivers installed.

J.,

I haven't seen this on my systems (Horus and either Native PMX, Sequoia, RX4 or MassCore PMX). It isn't always smooth sailing when changing SR or computers but no BSOD (he says, touching wood...)

Do you have the 'Auto' setting enabled on the setup/Format page?

Hmm. I wonder how much my non-Merging-spec pc is at fault here?

I've had Auto enabled, maybe I should try with it off.

Fortunately any instabilities I've experienced only seem to manifest while switching SRs or applications. Once everything is open and in actual use the Hapi and ASIO driver have been rock solid.

Thanks Graemme!

Also experiencing Sample Rate issues with Horus.

Horus previously worked fine with Sequoia a year ago.
Fresh windows install (Dec. 2014) - system was unstable.

New Horus firmware (24821) - system stable, but now Ravenna Easy Connect often displays:
"SDP Media Missing" error.

I believe we first experienced this error display after the windows re-install, but before the Firmware update.
Playback at any sample rate was not possible at this point. Reading the Firmware notes , one particular entry (22527) caught my attention. The version immediately previous (21673) was installed. Whether this is, in fact, relevant to our situation remains to be seen, however at the time I was convinced this was an appropriate explanation. ("Fixed. Timestamp of the first sample of a frame was not correct causing a problem with the RAVENNA ASIO Driver").

Following the firmware update (24821) playback at 44.1 seems fine.
However, playback at 88.2 and 96Khz is problematic.

The work-around we have discovered is as follows:
-Set appropriate Double Sample Rate in Horus.
-Open Ravenna Easy Connect
-Open Sequoia with a project at 2xfs
(test playback is optional, but not necessary.)
'Playback' occurs in Sequoia, but in red: "SDP Media Missing" displays in Ravenna Easy Connect, (and no physical playback present).
-Close Sequoia
-Re-Open Sequoia with same 2xfs project.
-Playback resumes properly (with no error message in Easy Connect).

Current firmware rev is 26178...

Current firmware rev is 26178...

Thanks Graemme. You are correct, it was released Mar 17th 2015. Will give it a try.

Must have accidentally looked at the Ravenna ASIO driver release date intead

...Anyone else seeing a similar crash...?

YES !
Just installed MaintenanceMode v32 and Horus Firmware (3.0.3) 26178.

Same "SDP Media Missing" error at 2xfs. The work-around described above still valid.

However, changed Horus to 44.1kHz and opened a Sequoia project at 44.1 (not sure if project sample rate in Sequoia matters or not).
HARD CRASH !

Hey J,

If you open Samplitude/Sequoia etc. for the first time at 2xfs, do you see a similar message in the Ravenna Easy Connect during playback?

[Graemme]

I'll try and replicate your crash steps with the Horus...(PMX, Sonoris, Sequoia 10 here).

OK...

Using the b26178 Horus firmware, PMX 9.1.6 (and beta 10) and the Ravenna ASIO driver v25336 (32bit), I do not experience the same crashes, following both J. and Andrew's methods.

[AndrewB]

Thanks Graemme for giving it a test drive.

Wonder if the 32bit vs 64 makes any difference ?
We have installed: Ravenna ASIO Driver Build25336 64 bit.

All my comments above pertain to Sequoia 12. (Pyramix is not in the equation).

Thanks for trying it out Graemme.

I wonder if it is specific to 64 bit as I'm on 64 bit here as well.

I seem to be encountering a fairly consistent and repeatable BSOD scenario:...

Have you made an official bug report ?

The most resent Crash yesterday was so Hard, the DAW was corrupted and had to be repaired/reloaded. Blue screen dump does mention the ASIO driver, and I have logged the error report (though will avoid posting it here).

This corruption has occurred previously, but not in the immediate past. Recently we did Windows 7 updates (though this should not be related). Nevertheless, I thought I would take the opportunity to test moving from 96 to 48KHz, and Bamm !

You need to call your dealer/distributor for proper support on this issue. If this is a bug it needs to be reported in order for it to get fixed.

Thanks Kjetil. The support team is looking into it.
At present, we are used to the workarounds, but it would be nice to resolve.

If anyone else has related scenarios, would be nice to know how isolated the situation is indeed.
