But if you are then please upgrade to the latest Ubuntu version and re-test. If you then find the bug is still present in the newer Ubuntu version, please add a comment here telling us which new version it is in and change the bug status to Confirmed. ** Changed in: alsa-driver (Ubuntu) Status: New => Won't Fix -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1605388 Title: [USB-Audio - USB Audio DAC, playback] Crackling sound with no original audio from playback in Chrome Status in alsa-driver package in Ubuntu: Won't Fix Bug description: When I begin playback in Chrome while using Pulseaudio, I get only cracking noises in my headphones, no original audio. Playback works correctly with e.g. aplay, mplayer, Firefox's plugin-container for Flash. If I unplug and replug the device several times, it will start working. If I disable Pulseaudio and use the ALSA hardware device directly (set the default in ~/.asoundrc; stop pulseaudio from starting; restart Chrome) then I do not experience this bug.
