The mixer is a bit weird - and probably different between CMI8329 and CMI8330. At least on my CMI8329A, the master volume does not work. And there are also some problems with PCM volume - I can decrease it in alsamixer but not increase - but it works both ways in XMMS... I have also some boards with integrated CMI8330 - so I might test it sometimes. > I don't think we would get many gain by changing this old code. > (and the relevant part isn't so big.) > Let's keep as it is. > > > Takashi > - > To unsubscribe from this list: send the line "unsubscribe linux-kernel" in > the body of a message to majordomo@vger.kernel.org > More majordomo info at http://vger.kernel.org/majordomo-info.html > Please read the FAQ at http://www.tux.org/lkml/ -- Ondrej Zary
