Audio issues

[Bob Zelin]

I have a new FCP Studio system with the G5 2.7Ghz computer running Tiger 10.4.2 and the AJA Io. I have loaded the latest drivers and firmware for the Io and I have an audio issue I can’t seem to resolve. The problem is very random. I hear occasional pops in my audio output and input, through analog and SDI. It isn’t captured with incoming media, but when I layoff a timeline it is laid to tape. Also, if I have Final Cut open and my audio board open to hear the output, I hear these pops randomly. Should I reinstall? Is the Io not compatible with the 2.7 Ghz G5 yet?

Hi Steve –
I have countless AJA I/O systems setup here with no audio popping. The audio popping or crackle problems that we saw were with the early AJA K-Boxes for Kona 2, not the I/O. IF its an AJA problem (thats a big if) – did you update the firmware for the AJA I/O? Download the AJA I/O control panel on the AJA support site, and when you open it, if it needs to be updated, it will say so on the bottom of the window in bright red. Once you do this, cycle power on the I/O, and try everything again.

The problem can be anything in your audio path – your mixer, your patch bays, the VTR itself. Check the firmware update on the I/O, and if it still does it, I will stop by. To directly answer your question – everyone here you know is using 10.4.2 with the AJA I/O and the G5 (yes, the 2.7’s – that’s what Ted and Greg are using at you know where).

Good to hear from you, Bob. Everything you listed has been covered. I’ve been trying to track it back through all the cabling and I’m having no luck. My next move was to call you. Stop on by.

Thanks,

Steve

When you solve the issue, please post your solution. I have had a similar problem on one of my G5’s, though I believe it will be solved with a ground loop isolator.

thx

We had the same problem and it seemed to be solved when we downgraded our firmware of our aja LA.

It was the Io, we had to swap it out for a new one.
