Re: [Alsa-user] how to convert stereo- mono signal during record
Is there some reason the application doesn't do mono? Almost all I've seen allow you to record only one track. Even on my MCP61, or my Mobile Pre. Which are stereo devices. You could look at audacity to see how it does it. Yes you're right, audacity can record only one channel with the alsa driver. The things is that when I call (err = snd_pcm_hw_params_set_channels(handle, hwparams, 1)) , the answer is err= 0, meaning it cannot set channels number to 1. And if I let it set channels number to 2, my application complains. At a minimum you should be able to split the track out after the fact. $ sox -c 2 stereo.wav -c 1 mono.wav avg -l No, as you say it's not usefull because I'm doing voice recognition in real time... Maybe not useful for you if you need to do realtime continous recording. Or something like voice recognition. But arecord allows mono recording from a stereo device. Here is what I get when running arecord to record a mono file : [EMAIL PROTECTED]:~$ arecord -D default -r 48000 -c 1 -f S16_LE truc.wav Recording WAVE 'truc.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono arecord: set_params:906: Channels count non available So nobody can give me an answer about how to do it with a .asoundrc file? Or is there something that I can do in the implementation of the alsa driver? - This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100url=/ ___ Alsa-user mailing list Alsa-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/alsa-user

Paisley Hi, I confirm, I have the Asus P5Q-E and have the same issue. I'm probably wrong but it seem that there is no driver for the AD2000B.

[Alsa-user] Recording problem, gentoo
Hello all Sorry if this turns out to be minor, but I have reached my limit of head pounding and googling. Should be simple, but I cannot persuade my system to record, or at least the recording has no sound. I can hear side tones from the mic, and they go off if I mute it, but nothing recorded with arecord. arecord -l gives: List of CAPTURE Hardware Devices card 0: CK8S [NVidia CK8S], device 0: Intel ICH [NVidia CK8S] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: CK8S [NVidia CK8S], device 1: Intel ICH - MIC ADC [NVidia CK8S - MIC ADC] Subdevices: 1/1 Subdevice #0: subdevice #0 alsa-info output is at http://pastebin.ca/1188423 Thanks for any advice.
