Hi,

Exactly. ALSA fireworks driver, a.k.a snd-fireworks, adds no control 
element sets in its control character device, thus you can no control 
elements with amixer or alsamixer.

I've been always explaining the reason as decrease of our maintenance 
effort in kernel side.

I continue to develop hinawa-utils[1] and libhinawa[2] for such 
application. However, as long as I know, there's no users in this world, 
just except for me.

Stuffs developed by ffado project are also available with ALSA fireworks 
driver.

Anyway, please have enough care of your permissions to firewire 
character device (/dev/fw*).

I note that ALSA fireworks driver still causes periodical noise due to 
protocol implementation. In detail, please refer to my former post[3].
