Hey, I´m an suse user with exactly the Same Problem. I got completely the same issue as reportados123, but i found a (not complete) "fix"!
I searched about this thing for Weeks and get stuck at the snd_usb_audio kernel module. I noticed the 'nrpacks' parameter of this module and start to play with it... and finally.... NO CRACKS. The Sound was fixed. But the Microphone get sometimes really worse like squeaking sounds or high Pitch. But in most use cases it works just perfectly. Here is what to do (I use opensuse 12.3, so i don’t know if it works for you..) 1. Stop any Application that uses ALSA or Pulse. 2. Open a Root shell (su, or sudo su) 3. type "killall pulseaudio" in your Terminal Emulator so long if it stops for auto spawn (yes, i know dirty but i´m lazy) 4. unload 'snd_usb_audio' with "rmmod snd_usb_audio". 5. Create an configuration file for 'snd_usb_audio' in /etc/modprobe.d/ echo "options snd-usb-audio nrpacks=16" > /etc/modprobe.d/audio- force.conf Note: For me works '16' as the Best Value. . 6. Now load 'snd_usb_audio' again: "modprobe snd_usb_audio" 7. Start pulseaudio again or just relog/boot. I hope it helps anyone! p.s: sry my english sucks :p (from germany) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1184025 Title: [USB-Audio - Razer Megalodon, playback] Underruns, dropouts or crackling sound To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1184025/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
