alsa-project/alsa-lib issue #163 was edited from markojurkovic:

There seems to be an issue with ALSA and some onboard Realtek laptop audio chips, in my case Realtek ALC233 (but I've seen some reports online of people with other Realtek chips facing this issue). Namely, I've noticed that I cannot make use of all the sampling rates that the chip supports in GNU/Linux using ALSA. The chip supports up to 24-bit/192kHz analog stereo output, but in the three Linux distributions I've tried (Ubuntu, Fedora, Manjaro) I can only get either 44.1 or 48 kHz. The problem manifests itself by throwing the following error when attempting to play, for example, a 96kHz file in Audacious:

"ALSA error: snd_pcm_hw_params_set_rate failed: Invalid argument."

If I attempt to play such a file using PulseAudio, I am able to play the file, but it gets resampled to 48kHz (which I've verified by running "cat /proc/asound/card0/pcm0p/sub0/hw_params")

In Windows, I can get up to 192kHz without problems using both WASAPI Exclusive and ASIO modes, meaning modes that directly communicate with hardware, just like ALSA.

Following is the output of running "cat /proc/asound/card0/codec#0". This output indicates that the only supported sample rates for the sound card are 44100 and 48000 (for the analog outputs), whereas this Realtek chip supports also 96000 and 192000.

Following is also the output of the alsa-info script: [alsa-debug.txt](https://github.com/alsa-project/alsa-lib/files/6797358/alsa-debug.txt)

I tried different kernel versions, both generic/mainline and custom, including the latest one (5.13.1) on distros ranging from Ubuntu 19.04, Ubuntu 21.04, Pop OS 20.04 and 21.04, Fedora 32...
