i have a problem with my mic here. Sony ecm-ds70p Stereo-MIC, BUT I cant capture in stereo with it. first i thought that my shity onboard-souncard has only a mono-input but now i realized that there in alsamixer, under "mic select" i have two options: "Mic1" gives me the left mic on both channels, "Mic2" gives me the right mic on both channels. So, how can I capture from those 2 mics together????????? i know its not 64studio specific, but i dont know where else to ask.

no, the mixer of the AC97-driver don't have L and R channel saperated. i tried out everyting in the mixer. i have some alternators wich i don't what they are for: "Mix" "Mix-Mono" "External Amplifier" "mono-output-select"-wich can choose "mic" or "mix"; but i playe around alot with those. i allready give up to have stereo mic-in with this driver/(pseudo)card

Same appears in envy24control

The mixer application envy24control that's spesifically designed for envy24-based soundcards has the same feature. For example input channel "pcm-capture_1" actually consists of two signals (L & R?) mixed into one. I have to mute either channel to get a separate mono signal. Apparently your card doesn't have a mixer to settle this problem?

You said you are using the on-board sound card. What card is it? The first step to better sound would be to look for a better sound card. There are lots of bargains to be had in second-hand computer shops. Also, that little sony mic is cool, but if you are looking for better sound you might need something better. Do not be fooled by mic profiling software etc. You cannot make a bad mic sound like a good mic via software, just as you cannot make a 2.5 tonne pickup drive like a ferarri by upgrading its engine management system...

i know that. I don't have money to buy hardware, don't even second-hand. my onboard-sound is AC97. But my goal is to buy a good card first, and than buy a better mic.

YES

i do use jack with ardour BUT in jack I get 2 inputs under "system": capture1 and capture2. but on both inputs there is only the signal from the mic that i choose in the driver, say only Mic1 or only Mic2 on both channels. So the problem is in the driver, where it is not possible to choose both mics together. The sondcard provides Stereo-mic-in but the driver doesnt - he treats the stereo mic as 2 seperate mics. and this mic i only can use on mic-in, so no way to use the line-in

Hi capoeira, What is your recording chain? If you use jack with ardour you might be able to select the two inputs simultaneously.
