Re: [Alsa-user] arecord: set_params:1239: Channels count non available

[Roger <rog...@gm...>]

=== Audacity ===
FYI: Audacity does have mixer/mixing options for selecting or recording only a 
Mono channel for the mic/microphone channel.

ie. "1 (Mono) Input Channel" or "2 (Stereo) Input Channels" 

=== Traceback into arecord (or aplay.c) ===
A little further into the source code of alsa-utils:

alsa-utils-1.0.27.2/aplay/aplay.c

@ Line 1238:
    err = snd_pcm_hw_params_set_channels(handle, params, hwparams.channels);
    if (err < 0) {
        error(_("Channels count non available"));
        prg_exit(EXIT_FAILURE);

=== English Grammar Corrections ===
1) Concerning the incorrect usage of the word " non ", the following should 
find all occurances of the word " non " which imply " not ":

fgrep /var/tmp/portage/media-sound/alsa-utils-1.0.27.2 -r -e " non "

2) Although "Channel count" is the correct English grammar form, I think the 
programmeres intentions were to make explicit reference to the variable 
"channels", or "--channels".

Following should find all occurances of the incorrect plural usage of 
"Channels", but I do not think this requires any correction!
fgrep /var/tmp/portage/media-sound/alsa-utils-1.0.27.2 -r -e "Channels count"
