arecord creates a lot of useless files

[ukicar]

When trying to record sound arecord produces a huge amount of useless files, only the first one in the chain has sound. Other thing is that program don't exit when duration of recording is expired. I'm afraid that our arecord has some kind of bug... tested the same program under Rpi where it works well
here is test instruction
cd /tmp
arecord -f cd -d 5 tt.wav

instruction means : record in cd quality duration of 5 seconds

What are the other files created ? Also .wav files ?

[ukicar]

yes exactly a lot of wav files that can't be read. Wave files 44bits in size not usable except the first one... I haven't see this behavior when tested on raspberry pi for example...
I couldn't find similar case on google

[ks156]

Is the behavior identical when the file is stored on flash, sd and usbFlash ?
And what's the name of the other files ?

[ukicar]

same thing!
other files are named with numbers name-xxx.wav

@ukicar can you please take a look at new version or alternative solution. Please research and advise how to proceed with this.

To be tested with the new openWRT version

How to over come the issue??any clue?

[drasko]

Is this re-appearing in the new version v1.2 as well?

[ks156]

I don't have an USB soundcard. @ukicar, can you try with v1.2 ?

I was struggling with this as well but this is these are the parameters that allowed me to record a 10 second wav file with no other files being created.

arecord -D plughw:1,0 -d 10 test.wav

Well I have some other bug that seems to record to the .wav file okay but doesn't output sound with I play or use sox to "play."
The weird thing is too is that sox's "play" command shows an equalizer bar that goes up and down as if sound is coming out but it really isn't.

So I can arecord with a -f command that outputs thousands of blank .wav files or I can leave out the -f and get a .wav file that seems to have when played with with sox but doesn't actually output anything.

The problem seems to appear on ARM architecture starting from 1.0.28 arecord version (arecord --version).
On Raspberry Pi 3 running Raspbian Jessie I had the exact same issue (creating bunch of files, not stopping after --duration seconds). Downgrading alsa-utils from 1.0.28-1 to 1.0.25-4 (rolling back to Wheezy's repo) fixed the problem.
