My Audio Devices
- Input: Logitech C310 webcam mic (16kHz)
- Output: Sony MBH20 Bluetooth headset (44.1kHz) in High Fidelity Playback (A2DP Sink) mode
With the default PulseAudio settings, the bluetooth headset sounds excellent, but recordings over the webcam mic are high-pitched and sped up, like an Alvin and the Chipmunks recording.
If I configure PulseAudio to set the sampling rate to 16kHz,
# /etc/pulse/daemon.conf default-sample-rate = 16000
then the webcam works perfectly, but the sound quality through the headset is severely degraded.
- Is there any way to configure the sampling rate for only a single source?
pacmd list-sourceserroneously reports the sampling rate of the webcam mic as 48kHz (
sample spec: s16le 1ch 48000Hz). Could that be the problem? If so, is there any way to manually change the sample spec? If not, does this qualify as a bug that should be reported to the pulseaudio maintainers?
- or is there another fix to this problem that I’m not seeing?
