Hi,
it seems that I found a (sort
of) solution.
Reloading the alsa kernel modules before
running arecord fixes the problem.
The command that I run is:
rmmod
snd-usb-audio && rmmod snd_usbmidi_lib && rmmod
snd_rawmidi && rmmod snd_pcm && rmmod snd_timer
&& rmmod snd_seq_device && rmmod snd_hwdep &&
rmmod snd && rmmod soundcore && modprobe soundcore
&& modprobe snd && modprobe snd-usb-audio
That
way, every and each execution of arecord gives a recording with clear
sound.

Hi,
I am running arecord on an Openwrt installation and I am
experiencing the following weird problem: if I record a sound two
consecutive times, the first time a lot of noise is recorded, and the
latter the sound is without any noise. It keeps going on this way (one
noisy, and the next one clear), unitl I close the terminal and open a
new one: then, it keeps going again that way - but with the order
"reverted", i.e. one clear, and one noisy.
Here
are the commands executed:
root@55:/opt#
arecord -f cd -r 16000 -c 1 /tmp/user_speech_18.wav
Recording WAVE
'/tmp/user_speech_18.wav' : Signed 16 bit Little
Endian, Rate 16000 Hz,
Mono
^CAborted
by signal Interrupt...
arecord:
pcm_read:2031: read error: Interrupted system call
root@55:/opt# arecord -f cd -r 16000 -c
1 /tmp/user_speech_19.wav
Recording WAVE '/tmp/user_speech_19.wav'

Here the

I
am using the following version of
arecord: arecord: version 1.0.28

Any
idea of what it is going on or any suggetion on how to figure it out?
Thank
you very much!
