audio blackout issues with ioHD
by

I've reverted back to firmware version 1.0, due to issues playing back rendered video. Since then, the picture looks fine in monitoring, but my audio dies after a while, for no reason and with no obvious pattern.

The only way to get it back it to reboot the ioHD and my 17" MacBookPro (2.4 duo, 4Gb Ram, running OS X 10.4.11, FCP 6.0.2). The audio will then play normally, only to die once again - could be 5 minutes or 20 minutes.

This, and the fact I can't bypass the ioHD to monitor audio via my MBPro's built-in audio output, makes my ioHD useless as a boat anchor in the desert.

Any ideas?

what storage are you using?


if you are running FW drives at the same time as the IoHD

<<< stop >>>

Working in HD over FW takes over the entire FW bus not leaving enough overhead for the Storage, working with this unit requires that you add an additional bus to any laptop you use it on.

worrying!

Did the v1 drivers work originally?

to Gary:

eSATA G-Drives Q (raided) via Express 3/4 card. Tons of through-put: no FW bus.

to Alan:

The v1 drivers worked originally: but I was cutting BRoll with no audio (it's all I was able to acquire - all shot MOS). So I can't say that the audio worked - I had no chance to test it.

I then upgraded to 1.1, and all hell broke loose. Video was all FUBARed in different and multi-colored ways. I was then able to digitize video & audio, and tried it briefly. I wasn't on long enough to see if it would die on me, as I was too frustrated re: video issues. I also did a full reinstall on FCP suite 2.

Any ideas?

Thanks,
Paul

I'm running a similar system to yours and will try and duplicate your problems if you post all your settings. I'm still on v1 drivers.

I'm in PALland and not with it at present so it may take a while though.

Thanks for that, Alan.

As for settings, I've tried two:

FCP:

Capture setting: AJA Kona 1080i60 DvcProHD to ProRes HQ
playback setting: Pro Res HQ (video plays nicely)
audio playback: AJA ioHD

Currently, I'm cutting SD video, and this is where the audio issue is at it's greatest.

video playback: Aja ioHD 525 29.97 8bit
timeline setting: DV/DVCPro Ntsc

Aja COntrol Panel: 525i29.97

Am I missing anything?

[Paul Huppe] "Currently, I'm cutting SD video, and this is where the audio issue is at it's greatest. "


Lets start over this post has me confused...

OS/ FCP ok

what QT are you running? 7.3.1???


if your cutting in an SD timeline, where did that footage come from?

Lastly

Have you contacted AJA Tech Support?

...and what's you reference set to?

Also, did you uninstall and reinstall the drivers, and did the firmware update when you loaded the new drivers?

I'd second Gary's comments about AJA support - second to none!

Sorry for the delay; I've been out of town and am only getting back to this issue. I'm in contact with AJA tech support, and they're stumped as well. We may be swapping boxes to see if that'll fix the problem.

I'll post an update in 2 weeks, as I'll be away from my suite once again.

Thanks all,
Paul

Hi

I'm on my second box now and am having the same problem, also an interesting one where I get get a "sample and hold" effect.

Have tried to return the firmware to 1.0 but the box refuses, how do I force it to reload firmware?

Have you downloaded the uninstall software from the AJA support page? That worked for me. Once everything's gone, reinstall 1.0 and it should work...

Update:

I've been talking to AJA tech support for the pas month now, and while he's trying his best and if very accomodating, we still haven't resolved my audio issue. It still dies intermittently, sometimes after 30 seconds of usage, and requires a reboot of my MBPro and ioHD.

Any new insight/ideas since the last post? Still hoping to keep the ioHD, but it's pretty useless right now.

Tim - would love to hear from you, as you said you had the same issue.

Cheers,
Paul

Did you try swapping the FW800 cable?
