Serious popping, clicking with USB DAC - Page 4

post #46 of 56

While this didn't work for the OP, I found switching to a different media player worked. With Foobar even light browsing would result in the occasional pop or click, and I could definitely make it stutter by opening up a bunch of tabs at once, but with MusicBee this doesn't happen at all.

Are you guys running any types of Anti-Malware programs? I had the static popping noise issue and I noticed that whenever I browse to different websites, I would randomly get that annoying popping noise. Using the DPC Latency Check mentioned in the first post, it showed my latency spiking up to high red bar levels. So then I went to disable every program that was running and I found out that by completely exiting and closing my anti-malware program called "Malwarebytes", the static popping noises went away and I'm consistently getting low latency green bars now. Looks like I won't be using that program anymore smile.gif

Hmm not sure. Have you tried playing with the foobar WASAPI buffer? I think it was mentioned earlier in this thread to use the hardware buffer, not the one in Playback > Output, but rather the one in Advanced > Playback > WASAPI > Hardware buffer.

Yes someone earlier in the thread mentioned disabling Antivirus programs as a solution for them, it didn't work for me though. I was using Avast.

Changing stuff around in Foobar isn't working. Itunes has the same problem.

I'm thinking it might be a power issue...

 

Laptop isn't popping or cracking either. No issues there. Same Antivirus so that can't be it. The USB port is even shared.

 

It seems I fixed it. No idea how.

hey guys. 

 

sorry for bringing up an old thread but i have the same problem and im just about to pull all my hair out.. i tried everything you guys suggested but with no luck. the problem started when i updated my video card driver and now i can find the original driver to roll everything back :/

 

my setup - intel dn2800 motherboard (everything is onboard..) and a MF V-DAC II

 

the problem - POPS! lots of them.. more when using youtube, less when using foobar - but they are alway there, mainly at the beginning of tracks or when i try to do other stuff (web browsing etc)

 

i also tried to check the IRQ and it is shared but i cant disable the other element:

any ideas on what to do next guys?

Didn't your computer come with disks with the original drivers? You'll probably find the graphics driver on it.

 

If not, then try plug your usb dac into another usb port, then check what devices it's shared with. They should be different.

it did, but i cant find them.. but even if i did, i updated the driver for a reason - playback of video files was slow and now its fine.. when audio is played through the hdmi output directly to the tv its also ok. the problem is only with the usb DAC.

Did you try different usb ports and check if there are differing IRQs with your dac?

post #55 of 56

i just did, i also made sure its the one that has no shared irq.. and the problem is still there :/

 

im gonna go for broke, format my computer and give it all a fresh start.. lets all pray to the audio gods it works.

For those struggling with the breaks in signal, here's another thing you may try:

 

The pops and cracks we hear are often resulting from the DAC buffer starvation: the DAC is running out of the stuff to play, because your computer has more important things to do than feeding data to some peripheral device. These "more important things" could be as trivial as waiting for your hard drive or network to respond...

 

The key to address this issue is to make sure that the DAC won't run out of data to process. One thing we can do to help is to increase the priority of this task. 

 

You may have heard that messing up with thread priorities can lead to instability of your computer. This is very true - if you take this too far, but elevating priority of one well behaving thread is not going to make any noticeable difference. And you do want to enjoy the music uninterrupted, don't you?

 

I'm a f2k user, so this is the domain I've been concentrating on, but the principle will be the same for other players, or even other platforms - you'll just have to find the specific solution.

 

In the f2k it is possible to change the player's thread priority, but in my experience this makes only marginal impact, if any. What you want to affect is the process of feeding the player's output to the DAC. In Windows this is one of the kernel activities and you're out of luck, if you have to rely on this mechanism. But there's also another way. This will not work in every situation, but if you've got the right toys it's worth a shot. There's one prerequisite: your DAC has to support ASIO, or better still - come with it's own ASIO driver.

 

Why is this important? ASIO bypasses the Windows sound support altogether and controls the DAC directly. Now, since the player controls the ASIO driver, it is able to set it's thread priority. And indeed - f2k allows you to use this feature by checking the "Run with high process priority" box.

 

I won't get into the intricacies of enabling and configuring ASIO - there are tutorials for that. Just wanted to point out that if switching between DS/KS/WASAPI doesn't make any difference, don't assume that ASIO won't fix it either.
