For the cards that do have this 32bit linear value, a simple lookup table is used in the kernel code to convert it to 256 step values.
Which driver is this? It should be changed to use the full range.
All creative and emu cards with a DSP. They use a lookup table in the driver.
Okay, with the latest driver, try: modprobe snd-emu10k1 high_res_gpr_volume=1
I did not yet enable this by default because alsactl has a bug when restoring mixer values saved by the old driver, and alsamixer currently thinks it is a good idea to let you step through two billion values.
