Yes, pcm data is 32bit and hardware is 24bit. Software will do the resample to 24bit to 32bit. It was fill 0 for extra bits.
South bridge (HDA bus) will set to 24bits. But the pcm format will be 32bits. You could look for Intel HDA spec.
does the plug-in extract the 24bit from each sample for sending to the HD-A bus?
No, it will be 32bit always. But your pcm data header will be 24bit.

Thanks for your clarification!
I can use “-D plughw” to record the S24_LE. Does this mean the samples over HD-A bus is 24bit when recording but the plug-in will pad each sample to 32bit?
And when playing S24_LE, does the plug-in extract the 24bit from each sample for sending to the HD-A bus?

20 and 24 was the hardware data format.
System pcm data format for 20 and 24 were S32_LE.
aplay -t wav -D plughw:1,0 test.wav => It need to add plug for -D. It will do the SRC.

主旨: Can HD-A codec Realtek ALC898 support 20/24 bit playback andrecording? How to verify this?
Hi,
I have a ALC898 codec. Can it support 20bit and 24bit playback or recording?
If yes, how can I verify this?
The audio input/output nodes show PCM bits [0xe]: 16 20 24
But I get error when using “-D hw” to record or play S24_LE format:
$ arecord -D hw:1,0 -r 48000 -f S24_LE -c 2 test.wav
