Hi, I'm very sorry to see your question only now, for the setting of recording parameters, you should need professional audio editing software to handle it, maybe this application can help you：https://github.com/audacity/audacity/releases

Changing a higher bit rate into Audiacity doesn't make your recording better sound quaility... see exanple
Still the "default bitrate" (32bit 44.1 kHz will be used...
The internal Intel HDA soundcard can record in 32bit 192 kHz, so I would like to change the " default audio bitrate" to the max setting possible....
I would like to know how the change it in Deepin OS
deepin I found the solution, in terminal type:
sudo nano /etc/pulse/daemon.conf
Then change it to these settings:
default-sample-format = float32le
default-sample-rate = 192000
alternate-sample-rate = 192000
(Crtl +O) to save
Now it works! I can record in Highest Audio quality

Hi all,
I would like to change my default audio sample rate to 32bit 192 kHz because I would like to record my Vinyl LP's
I have Huawei MateBook X Pro running Deepin Linux 20.5
I want to use analogue input, with stereo 3.5 mm mini jack cable which is connected to my phone preamp (cinch)
Can anybody help me to change the default audio recording settings to 24/32bit 192kHz?
I installed "Pavucontrol"
sudo apt install pavucontrol
But I can't change the default recording sample rate there...
