If you're wondering why we don't have a maestro3 driver, it's because
of its firmware. There is NO code under a suitable licence that we can
use. The FreeBSD driver uses a small file under the GPL. There's NO WAY
we can rewrite that file, because it looks like this:

/*
 * DSP Code images
 */

u_int16_t assp_kernel_image[] = {
    0x7980, 0x0030, 0x7980, 0x03B4, 0x7980, 0x03B4, 0x7980, 0x00FB, 0x7980,
0x00DD, 0x7980, 0x03B4, 
    0x7980, 0x0332, 0x7980, 0x0287, 0x7980, 0x03B4, 0x7980, 0x03B4, 0x7980,
0x03B4, 0x7980, 0x03B4,

However, this code was written by someone at esstech.

Maybe there are ways to tell this people, and other people at esstech,
that they could re-release this file under a BSD license, or better yet,
give us enough specs for their DSP so that we can write a clean maestro3
driver.

But do not bitch at us for not providing a driver, bitch at them. They
keep their stuff close-sourced, we don't get to have a free driver...
