Re: [Alsa-user] call for help: owners of M-Audio Revolution 5.1 cards

If the answer to both questions is yes, you could help to improve the ALSA support for this card by doing a little experiment: With ALSA version 1.0.12 or newer, recording with the card is supposed to work. In alsa-mixer you can find a capture volume stereo control. The problem: For me, left and right capture volume are interchanged. For example when I set left=0%, right=100% and try to record something from the microphone, I only get sound on the left (= wrong) channel. I would like to find out the cause of this problem. Possibilities: a) maybe I made a stupid mistake somewhere? b) or maybe my copy of the card is somehow broken in a weird way? c) or maybe it is a bug in the driver? So my question is: Can you reproduce this behaviour on your machine? This would help to rule out possibilities a) and b). Many thanks, Jochen I have 7.1, not 5.1, and there are no capture volumes, just the playback ones. There is no HW ADC gain control on 7.1. Can it be that your speakers are swapped (left - right) ? Or 5.1. is indeed more advanced ? By the way, typically microphone inputs are mono - the plug has only three wires - ground, signal and power - the latter is needed because PC microphones are typically electret ones. Stereo recording is expected to work from Line In input though. --Sergei. -- Visit my http://appsfromscratch.berlios.de/ open source project. - Using Tomcat but need to do more?

[Alsa-user] Non-blocking device parameters reading
Hi all!
I'm currently writing ALSA driver for one program. My wish is to read
abilities of the particular sound device and allow one to choose among
the allowable for the device. So my code attempt is following:
if (snd_pcm_open((d-soundfd), d-device, SND_PCM_STREAM_PLAYBACK, 0)
0) {
fprintf(stderr, Shit happens...2\n);
return;
}
if (snd_pcm_hw_params_any(d-soundfd, d-hwparams) 0) {
fprintf(stderr, Shit happens...3\n);
snd_pcm_close(d-soundfd);
return;
}
snd_pcm_close(d-soundfd);
And then analyse the hwparams object. This opens the device for the very
short time, but when the device is already opened (for instance, xmms is
playing) and doesn't support any kind of mixing (hw:0.0 at my CS4239),
the snd_pcm_open function hangs until the device will be released.
So my question is: may I obtain _any_ sound device parameters without
blocking? Or maybe it's possible to add the set of functions to alsa-lib
which will allow one to obtain info of the sound device without blocking it?
Thanks in advance,
Yury.

[Alsa-user] Help req rgd ALSA configuration scripts
Hi, Could somebody pl help me in ths regard. I would like to know why alsa.conf, asoundrc etc are required and are they useful in ALSA-native and OSS emulation modes. Can a simple system without spl features work without asoundrc or is it absolutely required? Where can I find these scripts and edit them? I'm new to ALSA and currently working on porting ALSA on an ARM based custom platform with a custom audio card. Pl help out. Regards Vishwas - Using Tomcat but need to do more?

[Alsa-user] Sound quality with SB Live 5.1
I`m new here and I`m sorry if this topic has already been exposed, the problem is: I use my SB Live (live line in) to radio broadcasting and the live input audio is very distorced.

Apparently, the controls are swapped, so ALSA developers have to look into this. However, if the card can't record stereo from microphone by design, it probably doesn't matter that much. 2) I used a stereo microphone which properly records stereo on a different sound card. Does this card (Revo 5.1) support stereo microphone ? What does user manual say about it ? Assuming you do not mute anything - can you really hear that the sound is stereo from the microphone ? The microphone probably has two heads, so tapping on one of them should produce loud sound in that channel and silent one in the other channel - is this the case ? I mean, if the card is designed to provide power to electret microphone through the 3--terminal 3.5mm jack, it can't support stereo.
