Why is the AC97 format set to S16 in all of the drivers? The link is 20b and my codec takes 20b, how do I get 20b data to the device?
You can only use sample formats that are supported by the AC97 controller.
I tried using SNDRV_PCM_FORMAT_S20_3BE but all I get is static.
S20_3LE could in theory be used by USB devices. There is no hardware that supports S20_3BE.
How did you use this format? Which driver is this?
If I use S24 for the format it works but volume is divided by 16.
S24 means that the 24 sample bits are in the least significant bits of a 32-bit memory word. 24 sample bits in the most significant bits of a 32-bit memory word would be S32. (It might be possible that your driver gets this wrong.)
