VO-BB - 20 YEARS OLD!

[stugray]

I had a power supply in my computer that was burning up...I took my box to the shop yesterday and they put in a new power supply, plus USB 2.0 (I only had 1.5 outlets...)

Now, the computer is back in the house...

Plugged in: Mic to Avalon preamp to m-audio box to computer usb.

I am getting pops and clicks all over the place when I record.

I have reinstalled the m-audio/mobile pre driver.

I have plugged, replugged, unplugged, and plugged some more. Every combination of XLR swap out available.

When I plug in my mic to the Micport Pro then into the USB, there is no clicking or popping while recording.

I didn't change any settings on the Avalon, or the Mobile pre Box...I did move my gear across the room ( I got a new studio desk, and thought with the computer out of the house, I could do some quick revamping of the room.)(pictures to come later. If I get this thing figured out

Anyone else had this experience?

HEEEEELLLLLP!!! Thanks!!!

When I first read your post, my initial thought was a buffer issue. Have you tried raising the hardware buffer for the mobile pre?

Does it do it with both the USB 2.0 and 1.5 ports? If it's just the new ports, maybe they are the problem. I'm assuming the older USB ports are on the motherboard and the 2.0 ports are on a recently installed PCI card. If that is the case, maybe there is a hardware conflict with the PCI USB card. Maybe it's sharing an IRQ which could cause problems.

The buffer issue was my first thought too. It seems like that problem has been addressed on this forum before. You might want to do a search.

[stugray]

Do you mean within my recording program (Adobe Audition)?

I have not messed with those buffers just yet...but I am going to see if that helps.

Thanks! - stu

I will check it out for sure thanks Gp

You have wireless on that computer? Turn it off if so.

Hey Bob - I do have wireless...and I do turn it off! Thanks for the input.

I did figure it out, and it was the latency settings in the m-audio mobile pre hordware/software on the computer.

After the computer was repaired, some setting adjusted the latency to a lower rate, which caused pops and clicks. I had to keep adjusting the setting til I found the correct one.

Thanks for all the help!!

Buffers, hardware conflicts, networking, and ASIO problems are the usual culprits.

Buffer settings will change with each set-up, try going higher and lower. ASIO latency will also be a hit and miss situation.

USB connections have some inherent problems with compatibility issues. Some chip sets are not compatible with certain PC or Mac chip sets.

When using wireless networking, turn off the internet and ALL anti-virus programs as they cause problems such as you indicated.

Additionally, with AA you may need to place your temp folder on another hard drive. Due to the inherent nature of AA (2.0, 3.0 particularly) an outboard hard drive with a Temp folder placed there minimizes hard drive interaction.

Since the MicPortPro works with no noise, I assume from the explanation given it is the buffering within the MobilePre, not a USB or wireless networking problem. You may also find you are driving the soundcard too hard with the pre-amp.

The MicPortPro has it's own sound card, so you would not be using the Avalon, correct? Thus a process of elimination may be needed to figure out where the problem resides... take one piece at a time out of your chain and record. Listen. Then determine if you are still getting the "fault". Replace the piece of equipment in the chain and take another out. Do this until you find the problem.

Good luck.
