Urgent Help needed

Hi All,

I'm using Audio PCI 1371.
I need to know if I can program both MIC and LINE IN in capture mode
simultaneously. IF yes how.


Thanks & Regards
Shakul

no, on ac97, you can use only one of the capture sources at the same
time.  (or, two single mono captures are possible by assiging left and
right channels to different sources.)

another possible solution is to capture from the "Mix" source, which
is the mixture of all playbacks, including mic and line-in.
however, the quality may be bad, and of course, the signals can be
contaminated by other routes.

Hi,

Please if you can help how can I program the device the "MIX" mode for both
LINE IN and MIC capture. I accept that both the 
inputs are to be capture in mono, in stero mode the quality will be bad.

If you can refrence to some API calls and structures.

Check either alsamixer or any other ALSA or OSS compatible mixer. on
the same global volume send sliders you should be able to also set the
record option. You should also play with the IGAIN slider to adjust
the input volume rate for recording. One of the things that surprised
me the most about the ensoniq 1371 cards is the amazingly clean ADC
compared to my other cards. If you have your computer and whathaver
you are using as input source well connected and properly grounded,
you should get no noise at all while recording. So far i've been using
it as cheap analog source recording, connected to a mixer, which has
connected a couple of synths, and the results were extremely good.

Thanks Juan, Takashi

Recently I wass going thru AC-97 Component specifications. It seems that it
is possible to bypass mux for MIC input and have two captures
simultaneously.(Section 5.5 pg 45 AC97 Component Specs). I don't know if it
supported by any driver.

Please if some one can send some documentation on mixer and groups. Was not
able to locate any good documentation on how these works.
