I have a slight sort of crackling noise coming through my headset when I play, well, anything. It doesn't seem to happen if I just open a youtube video and let it play, not touching ANYTHING else. But if I maximize and minimize a couple times it starts up (or if I am doing anything else on the comp e.g. chatting on steam).

I am new to Linux and I am using my SteelSeries Siberia v2 USB headset which has it's own usb sound card 7.1 simulator thing. More info here: http://steelseries.com/us/products/audio/steelseries-siberia-v2-usb

I tried editing pulse settings but I can't seem to get permission to do that. And I looked up how to just delete pulse and ended up deleting a bunch of stuff I shouldn't have and then had 0 sound and no system settings...I reinstalled everything is back to where it was.

Is there a workaround for this?

I had horrible clicking/popping sounds from my Logitech G35 USB headset. It worked fine on windows but not Fedora. There would be a painful sharp crack every now and again when music was playing, and every time I'd seek to a new spot in a track or on youtube.

The following additions to /etc/pulse/daemon.conf seems to have improved things, although I've only tested for about an hour. These options increase audio delays/buffer sizes, and reduces the sampling rate. It's pretty severe, so if it works start playing with the numbers to find a balance. Not sure which option is the main suspect yet.

resample-method = src-sinc-best-quality
default-sample-format = float32ne
enable-remixing = yes
default-sample-rate = 16000
deferred-volume-safety-margin-usec = 16000
default-fragments = 8
default-fragment-size-msec = 60
nice-level = -15

After saving, run pulseaudio --kill, pulseaudio --check and pulseaudio --start if no errors.

Update: Pretty sure the 16khz sampling frequency essentially removes the crackles with a low-pass filter. Ugly quality, but better than aching ears.

This sounds similar to a known bug and does not look to be fixed any time soon. I have a similar problem with a USB DAC adapter. There is a bug raised at launchpad (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1136110) but the only recommendation so far is to attach the device to a separate PCI USB2 device, not USB3, however even this is not guaranteed.

I have just ordered such a card from eBay and will hopefully see if it helps me soon.

I'm not an expert, but I solved my problem:

  1. Going to the Ubuntu software center
  2. Dwnloading Pulse Audio Volume Control app
  3. Setting my Internal Audio profile to Stereo Analog Output rather than Analog Stereo Duplex.

If you wanted to get permissions, it's very simple to become the root user. Simply open the terminal, type sudo su and enter the password to use to log in. Then you can change your pulseaudio settings.
