[Desktop-packages] [Bug 1605388] Re: [USB-Audio - USB Audio DAC, playback] Crackling sound with no original audio from playback in Chrome
The non-working case loops continuously through creating and freeing inputs just under 21 times/second. It's not clear to me whether this is a Chrome bug or a Pulseaudio bug. Any help in determining which one is the cause would be appreciated. -- You received this bug notification because you are a member of Desktop 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: New Bug description: When I begin playback in Chrome while using Pulseaudio, I get only cracking noises in my headphones, no original audio.
