Make sound bad on purpose?

I intentionally want to set the sample rate of my sound chip (not microphone, but speakers) in the laptop low. With PulseAudio (Linux) nothing changes when I play with the configuration, under Windows only at least 44.1 KHz can be selected.

Hence my question: What other possibilities are there?

There it doesn't matter whether it is a browser extension, registry mod or application, for example.

Which sound driver do you have installed as standard?

E.g. "Realtek" is often used.

Should be a Realtek audio chip.

What does this list look like for you?

Similar, but with me everything from 8000-32000kHz is missing.

Please see if you can find the Management EXE from Realtek.

C: \ Program Files \ Realtek
Or where you installed it.

This is another way of making audio settings.

What are you trying to achieve Today's sound chips usually support sample rates lower than 44100Hz. Not. And many programs also find it difficult to feed such low channels.

You can simulate the reduction of the sample rate with a steep low pass with a filter frequency = half the sample rate but tonally.

With pulseaudio you can switch in LADSPA plugins (under Ubuntu a thick package with such: sudo apt-get install swh-plugins) as virtual devices:

$ pacmd load-module module-ladspa-sink sink_name = limiterx plugin = fast_lookahead_limiter_1913 label = fastLookaheadLimiter control = 0.0, -12,0.16
$ pacmd set-default-sink limiterx

It's for a limiter and not a low pass, because I don't have anything else ready. The plugins are all addressed in the same way.

Maybe still helpful for a steep "digital" lowpass, as you could use it for resampling:

If none of this has any effect, pulseaudio may be incorrectly configured so that the audio signals pass it or something similar.

I used this technique to create a Teamspeak scrap sound fixer script that I start once and then everything comes out of the loudspeakers at the same volume, so that I don't always have to adjust the volume. I use that every day and these Ladspa stories usually work. Reliable.
