I've now finally gotten an Analog Devices ad1988B with six in and ten out + digital - all in glorious 24bit/192K, which I find mighty impressive for an onboard three dollar chip. The sources for alsa-1.14 were included on the CD that came with the (Asus) box, and this is also what I am using now.
The driver has fixes and workarounds for various note-book configurations with built in speakers and microphones as well as various numbers of physical multi-purpose ports that connects to the outside world. Unfortunately nobody thought of the possibility of a vendor wild enough to actually simultaniously implemement /everything/ this chip has to offer. Surround 7.1 on the "six-stack" on the backside is supported by alsa, but appears to then replicate the "surround front" to the headphone socket on the physical front panel which may or may not be what you expected. Getting skype and friends out of the mix - perhaps even on its own little /dev/dsp1 for closed source legacy? - would in my opinion have been more like it. Any ideas how to solve this? There is no such ugly invention as "surround 9.1" nor "surround 7.1+2" as of yet ... But that could of course be changed :-) I have some other minor issues as well, like the headphone amp being activated on the backpanel port labelled "line" but not on the frontpanel jack labelled "headphones" ... But those appears to be comparatively trivial to fix by comparing to how all the other special case configurations are implemented. -- _______________________________________________ Linux-audio-dev mailing list [email protected] http://lists.linuxaudio.org/mailman/listinfo/linux-audio-dev
