Headphone out (mobo) Displayport audio out (amd gpu) Headphone output works if default-sample-rate = 44100 in .pulse/daemon.conf, whereas displayport only works if default-sample-rate = 48000. It does not seem that having alternate-sample-rate set to the alternative value of default-sample-rate makes any impact.

PulseAudio can operate using two different sample-rates by configuring default-sample-rate = 44100 alternate-sample-rate = 48000. Some documentation indicate that this is supposedly good if you play some CD audio with a 44.1kHz sample-rate and some movies/musicvideos with a 48kHz sample-rate. It is not. Sound cards and HIFI equipment (when using HDMI) can only be …

By default, PulseAudio (PA) uses very conservative settings. This will work fine for most audio media as you will most likely have 44,100Hz sample rate files. However, if you have higher sample rate recordings it is recommended that you increase the sample rate that PA uses. In /etc/pulse/daemon.conf add: default-sample-format = s32le default-sample-rate = 96000.

Show activity on this post. I have a Logitech C310 webcam, which pulseaudio believes has a sample rate of 48 kHz. However, the hardware only works at 16 kHz. Most applications will try to use the 16 Khz audio at 48 kHz, resulting in a high-pitched squirrel or chipmunk sound. This happens across a range of applications, and in Windows as well.

sample rate can be set in daemon.conf, but that's probably not what you want. If pulseaudio can't open the device by default, you should be able to create the source just by inserting this line somewhere in your default.pa: load-module module-alsa-source source_name=mic device=front:<alsa card index> rate=16000 That should be on one line.
