audio - Set pulseaudio sample rate for a single source ...
https://unix.stackexchange.com/questions/388127/set-pulseaudio-sample-rate-for-a-single-source
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.

Pulseaudio settings adhere to the sink they are made for. Hence we are able to read the values we gave with the following command: pacmd list-sinks This will give a rather lengthy list including the following information similar to this. sample spec: s16le …
Audiophile – PulseAudio
https://www.freedesktop.org/wiki/Software/PulseAudio/Documentation/User/Audiophile/
PulseAudio. 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 …
Alternate sample rates – Arun Raghavan
https://arunraghavan.net/2011/10/alternate-sample-rates/
These introduce the concept of an “alternate sample rate”. Currently, PulseAudio runs all your devices at a default sample rate, which is set to 44.1 kHz on most systems (this can be configured). All streams running at different sample rates are resampled to this sample rate.
[SOLVED] why isn't pulseaudio switching to "alternate ...
https://bbs.archlinux.org/viewtopic.php?id=227519
As i understood, the config option alternate-sample-rate should make pulseaudio switch to a different sample-rate when there is only a stream connected to the output that matches that value. I prefer to keep the default to 44100 to hear music and just switch to 48000 when i watch movies.

1.1 User client configuration file example. 2 Set default input source. 3 Set the default output sink. 4 Set the default output sink profile. 5 Independent analog and digital outputs on the same card. 6 Simultaneous HDMI and analog output. 6.1 Alternative solution using module-loopback with delay compensation.
PulseAudio - LinuxReviews

PulseAudio will up or down-mix the source audio to the set sample-rate and then up or down-mix to the sound cards highest supported sample-rate. This means that if you set default-sample-rate to 96000 and you play 44.1 kHz on a sound card with a 48 kHz limit the audio gets up-mixed to 96 kHz and then down-mixed to 48 kHz.
Configuring Linux ALSA/Pulseaudio for best sound
https://hydrogenaud.io/index.php?topic=94080.0
I don't think ALSA does any samplerate conversion if PulseAudio (or especially Jackd) is being used, as PulseAudio uses direct access to the card but Pulse has a few audio settings that change the sample-rate conversion algorithm, and default sample rate Not in Linux at the moment so bare with me, /etc/pulse/daemon.conf should have settings in it
PulseAudio under the hood - Victor Gaydov
https://gavv.github.io/articles/pulseaudio-under-the-hood/
PulseAudio implements various sound processing tools, like mixing, sample rate conversion, and acoustic echo cancellation, which may be employed manually or automatically. Sample cache PulseAudio implements an in-memory storage for short named batches of samples that may be uploaded to the server once and then played multiple times.

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.
