    mysterious popping and clicking through AM/Console but not directly to sound card.

    Alright I got a bit of a weird issue that I havent been able to solve for a long while.

    I am running an Asus Xonar D2x card using audiomulch, VAC, and ASIO for processing. I have been running the same setup for over a year now and everything works just as it should, but I still have pops and clicks in the audio that I can mimic every time. First starting the computer and starting audiomulch and winamp there are no clicks, but after 5-10 minutes they start and are very random, seems to be a bit random with the start time as well. The way I have fixed it is just to reset the audio in audiomluch, just hitting the "Enable audio" button off and on and no more clicks, but obviously that gets pretty annoying after a while.

    I have tried just about everything I have seen others try when troubleshooting clicks and pops:

    -Checking DPC latency check (never goes above 700 micro seconds)
    -set audio/processing programs to high priority (even did real time)
    -tried different buffer settings through audiomulch/ASIO/winamp
    -tried other output plugins through winamp (ASIO, Kernal Streaming, directsound)
    -made sure windows power settings were on high performance and processor was always set to 100%
    - checked BIOS as well to make sure it was limiting anything
    - tried different audio players.
    - Have taken it out of the car and tested it with a different power supply
    - tested it on home audio system
    - Have even changed motherboards from ITX to micro ATX (wasnt troubleshooting here, just changed as I wanted more expansion slots, but thought it was worth mentioning)
    - I have setup Windows XP 64-bit instead of Windows 7 64-bit
    - Tried setting up Console instead of Audiomulch and still the same behavior
    - cut out audiomulch and console and went directly through winamp to the sound card with no popping and clicking (doesnt help me through since I need the processing)
    - Used onboard sound through audiomulch/console and no pops or clicks.
    - Checked power connection on Asus card and they seem ok, will try re-soldering connections incase they got loose but that will be last resort.


    I am sure I missed a few other things I have tried but those are the ones I remember and have done recently. As you can see the problem is the same whether I am using AM or Console and only does it with the Asus Xonar D2x and not the onboard sound, but yet the Asus card will work fine going directly to it through bypassing AM/Console. If anyone can help me with this issue, its baffled me for a long time now, I have it in the house right now so I can better test everything before I stick it back in the car. Dont hesitate to mention something trivial that isnt mentioned.

    Thanks ahead of time!

    using your current setup, try using the wdm driver for the soundcard, and vac as the source(like in my how-to) and see if that also has a issue. i believe that should be ok, proving that it would be a asio buffer issue..

    hmmm, I didnt even think about the drivers, good call.

    Well I uninstalled all the asus software and just installed the drivers via Device manager, but now it wont decipher 8 channels, they all output the same no matter how I set it up in control panel -> Hardware and sound -> Sound. There something else I am supposed to do?

    Alright well I seen that in the xonar control panel (when fully installed) shows by default the analog out is set to stereo 2 channel rather than 7.1 to enable all 8 channels. So when I uninstall those drivers and just do the WDM drivers it defaults to that two channel analog out so everything outputs on the "front" connection on the card no matter if ASIO shows 8 channels, all those connections just go out the "front" connection. I havent seen anywhere else how to change this without installing the asus control panel.[COLOR="Silver"]

    this is kind of like the blind leading the blind-- i have never used that card, so this is mostly a shot in the dark..

    you might need to install the asus software to allow the pc to see all the channels.

    also, if your card has internal routing, you can use the ASIO drivers, and should be able to ditch VAC..(so all you would have to configure would be the soundcard, and AM)


    i used to have odd popping on my old atom board-- a intel 945glc--whenever the board went above 35% cpu. at the time i was using vac-->A4A-->console, i don't believe this is part of your issue, but just posting it up in case it might be of some help.

    From what I understand of others who have this card, you cant do internal routing with this card. But yeah, I am afraid that I might have to have the asus control panel to adjust that unless I can find some drivers that force it to 7.1 by default or there is some adjustment I can make somewhere to easily do this.

    But just doing the WDM drive only install I did play with it a bit and have yet to get any clicks, even though I can only use one output on the card itself so I think thats the solution, but I will have to test it some more to make sure.

    Well I spoke too soon. It just took longer for the pops and clicks to start , but they are still there

    I kind of doubted that it was the software because it worked just fine going out directly and bypassing AM/Console. As far as your other suggestion, my CPU is a C2D E7500 2.93Ghz and it rarely goes above 20% when running everything, including navigation, wifi, etc...

    Anything else to consider?

    i really don't have a clue...

    comparing both of our setups just in case some of it matters:

    mine uses a pentium dual core, and esi gigaport-- a usb soundcard, and am using VAC w/ AM using 'windows multimedia' setting(wdm driver), and have zero pops..

    yours uses a c2d(better), and pci-e card(better), and have tried all sorts of different software tweaks...


    i would say there could be a issue with the card...

    Yeah, i am at a loss as well.

    I am using VAC w/ AM but using ASIO4ALL so that I can still use the inputs of the Xonar card plus the onboard sound in conjunction. 3-way up front, plus sub, plus two-way rear requires 12 channels and the line-in is for RTA stuff.

    I can do Windows multimedia for just VAC input and the Xonar ouput and it will still click and pop, no matter how I set the buffer, the buffer only changes the time that it will start to pop and click.

    I am at my wits end right now This issues has alluded me for over a year now.

    ok, the only common denominators are the sound card, and vac, and being that the soundcard is still working, and it is really unrealistic to think that the sound card would cause popping-- otherwise, that would pop up in the reviews for the card...


    vac is the last thing that can be wrong..


    and a easy way to confirm this would be to send the audio directly to the soundcard-- bypassing vac, and AM.

    and i assume that you also have this issue with the onboard? if you haven't specifically noticed, it might be worth trying to use vac+am with the onboard sound, and then verify that the popping disappears by bypassing vac+am..

    and one last thing to try-- bypass all plugins in AM-- so the audio is getting routed through vac+am, but with no manipulation(i haven't run across any plugins that cause the issues you have, but have used some really poorly-coded crossover plugins that will not pass audio at certain settings, so i imagine that other poorly coded plugins could also cause weird issues)


    i also started browsing the manual, and found this in the trouble shooting portion, granted, some of this you have already tried, but at this point, it is all worth a shot:

    There are cracks and pops while I pass my sound over a Virtual Cable. How to get rid of them?

    If Virtual Cable is the only path between two applications (one is playing back and another is recording), try the following:

    If your application uses DirectSound, check and adjust the DirectSound hardware acceleration level.
    Check the CPU load and try to lower it if high.
    Try to stop unnecessary application activity.
    Try to increase the buffering time in audio application.
    Try to decrease the number of milliseconds per interrupt parameter for the cable.
    Try to enable load splitting among CPUs/cores using registry parameters.
    If there are other (hardware or software) devices in the path (for example, an application records from a device and plays back to Virtual Cable, or vice versa), please also check if this issue is not caused by clock difference.


    definitely check the vac manual (document with the '?' icon)-- the area i copied is about halfway down the page in the 'trouble shooting' section, and is full of links to other terms/paths..

    good luck, and happy hunting!!

    As I stated above, it works fine going directly out through the Xonar card, taking out VAC and AM, but it also works perfectly through VAC -> AM -> onboard sound.

    And yes, I have tried just doing sound in to sound out without any plugins and still does the same thing.
