Hi Alexander,

I got the sound out of that speaker!! :)

I actually started to read your code, and I'm still trying to understand
the stuff in it (I never wrote a device driver)

Anyway, so I did a little hack'ish modification (just to test) in function

hdaa_audio_ctl_amp_set_internal(struct hdaa_devinfo *devinfo, nid_t nid,
					int index, int lmute, int rmute,
					int left, int right, int dir)
	uint16_t v = 0;

    // Do not mute, even if asked for. Test to be removed of course
    lmute = 0;
    rmute = 0;

I know, this is absolutely NOT the way to do it, but I wanted to see
if the speaker wasn't muted (or the mixer that controls it)
and it -actually- WAS muted!

Now, I guess I'll have to read the whole code, try to understand its
internals, and I hope to be able to write a patch to add to hdaa_patches.c

I'm just a beginner, but I'll try anyway :)
