Can't play 44100hz, 88200hz files Natively.

Can't play audio files at native sample rate. Everything using the Hifi 2.0 output configuration forces a sample rate of 48000hz. When I switch to the Pro Audio driver under pavucontrol, 44100 hz can play natively. Is there a forced resampling occuring in the UCM2 driver?
perexg commented
Which hardware are you using?
RenEH01 commented
Sorry, I should have mentioned it earlier. Realtek 4080 on the MSI b650 Mortar Wi-Fi board.
perexg commented
There is no forced rate or resamling specificed in the configuration file for this hw - https://github.com/alsa-project/alsa-ucm-conf/blob/master/ucm2/USB-Audio/Realtek/ALC4080-HiFi.conf . We had some issues in the USB driver (rate lock when the first device is opened for the given USB sound card), but they should be fixed in the latest kernels. Maybe there's something left. Does "Pro Audio" open only the playback device ? You may check this in procfs - cat /proc/asound/card*/pcm*/sub0/*. Also, which kernel version are you using?
@tiwai : FYI...

Thanks, I am on 6.1.26-1-MANJARO.
I'm not too sure what you mean, but please see below for cat /proc/asound/card*/pcm*/sub0/* when Pro Audio is selected under pavucontrol.

I don't know if this is helpful. but when Hifi 2.0 is selected in pavucontrol this is listed by the same command as above.

I see 44100Hz in both outputs. You can filter the output only for the problematic card - use aplay -l to list cards and devices eventually cat /proc/asound/cards will work.
RenEH01 commented
I see 44100 as well, but my DAC displays the current sample rate and selecting Hifi 2.0 puts out only 48000hz to the DAC.
perexg commented
It's weird, but it looks like an issue somewhere else (maybe the USB card does some hidden resampling?). The alsa-lib/ucm does not hardcode the rate for this device. The procfs values are from the driver, so the user space sets the rate correctly.
RenEH01 commented
This is a built in motherboard solution. If switching to pro audio fixes issue, I don’t think it’s a hardware thing. Could it be that in the driver somewhere it thinks the Realtek 4080 can’t do 44100hz?
perexg commented
If the 44100Hz is in procfs then the user space already sets to this rate and the driver should issue the USB rate command to the hardware with this settings. You may check the rate settings sent through USB using the dynamic debug for the snd-usb-audio kernel module (dyndbg=+p argument). Like:
echo "options snd-usb-audio dyndbg=+p" > /etc/modprobe.d/alsa-test.conf
# and reboot ...
Look to dmesg for the debug lines..
RenEH01 commented
My previous OS was a clean install of the latest Manjaro build and this issue was present. I now have a clean install of Ubuntu and 23.04 and the issue persists here as well. The pro audio work around does not work with this OS.
Sorry, I don't know what you mean to do with:
echo "options snd-usb-audio dyndbg=+p" > /etc/modprobe.d/alsa-test.conf
and reboot ...
Should I just cut and paste that in my terminal?
