There's no default sampling rate that solves or significantly reduces this problem for me.
My device is a FiiO E10 USB DAC. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1067466 Title: Sampling rate issues with M-Audio MobilePre usb audio interface Status in “pulseaudio” package in Ubuntu: Confirmed Bug description: Plugging an M-Audio MobilePre USB sound device into several Ubuntu and Ubuntu-drived installations consistently results in incorrect audio playback. Playback was fine until 11.04 I believe, after which I believe the kernel jumped to a new major revision, and it hasn't worked out of the box on any Ubuntu or Mint-based systems since. The device is currently plugged in to a Mint 12 system: uname -a prints: Linux ctn00 3.0.0-26-generic #43-Ubuntu SMP Tue Sep 25 17:19:22 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux I don't know how to diagnose the problem (I don't see anything obviously wrong in dmesg), but I am happy to check things that devs believe to be diagnostic. I've tried playing to the pulseaudio device from several sources: speaker test, chrome browser, and Mplayer... sound issues are the same for each player. Two workarounds I've found are (a) Open the sound settings window in e.g. Ubuntu's default window manager / graphical environment, which I think is a pulseaudio control center. Switch tabs and select the MobilePre as Output and Input device (even though it was already selected... just go back and click on it), and LEAVE THE APPLET OPEN. If the Applet closes, then sound goes to hell, but as long as the applet is open or minimized, then it seems to keep things going (very strange). This results in perfect playback. (b) Open /etc/pulse/daemon.conf file, set the default sampling rate to 48000. This tip was gleaned from an ArchLinux wiki page on PulseAudio. It makes sound playback *almost* correctly, but there is still a hint of static / sampling noise that occurs somewhat sporadically. This workaround doesn't require having a dummy window open, but also doesn't entirely solve the problem.
