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 [EMAIL PROTECTED] > More majordomo info at http://vger.kernel.org/majordomo-info.html > Please read the FAQ at http://www.tux.org/lkml/ -- Ondrej Zary - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

CMI8330 has a dual interface for SB and Adlib modes. The mixer can also behave differently according to the mode. The current code has mixer elements corresponding to both modes. However, these mixer elements _seem_ to interactive with each other, and cannot be controlled individually. That's why ENABLE_SB_MIXER is disabled. I cannot check this issue any longer since the test board got broken long time ago... I don't think we would get many gain by changing this old code. (and the relevant part isn't so big.)
