Title:
Noise in left channel with USB audio device
Status in pulseaudio package in Ubuntu:
Expired
Bug description:
Binary package hint: pulseaudio
I keep hearing (white?) noise in the left channel of my headphones
through a USB audio device.
I just noticed it start in the middle of playback.
I killed the /usr/bin/pulseaudio process, waited for it to re-start,
and that made the noise go away.
Power cycling the device repeatedly does not make the noise stop.
The device is, from lsusb:
Bus 003 Device 002: ID 08bb:2900 Texas Instruments Japan PCM2900 Audio
Codec
It's a HeadRoom Total BitHead.
