description |
In Intrepid and Jaunty, audio sent through the Plantronics DA40 is distorted if the per-application volume is above around 80%. Unfortunately, all applications default to 100%. Audio sent directly to the ALSA device is not distorted, so this is something happening in pulseaudio. I attempted to test this under Karmic, but the volume sliders behave very differently, with the pavucontrol sliders adjusting the ALSA "Speaker" mixer, and I was unable to remove the distortion at all.
The DA40 is a mono device, so perhaps it's a problem with pulse downmixing stereo audio to mono without reducing the per-channel level, resulting in clipping. but I tested with a DA45, which is a similar mono adapter, and the problem didn't exist. |
[SRU Justification]
Impact: See below. But in short, distorted sound when on an analog-mono profile. Most soundcards support analog-stereo only, but for some hardware, this is a problem.
Testcase: Using hardware that supports analog-mono profile, play back audio, source
material at sufficient volume. If this bug is fixed, there is no distortion.
Regression potential: Can't think of any, and if so, it should only affect downmixing to mono, which is unusual anyway.
