aplay/arecord start-up error

aplay/arecord start-up error

[Igor Gueths]

Hi all. I can play audio fine, however when I went to try to experiment
with arecord, I got the following: main 445: audio open error:
inapropriate ioctl for device. Anyone have any ideas as to what I could be
missing or doing wrong? Thanks!

[Gregory Nowak]

Yes. I've posted this same problem twice on this list; once a couple of months ago, and again a couple of weeks ago. It was Chuck H. that rtold me that I needed to pass flags other then the file name to arecord/aplay in order to get it to work at all (something that was not obvious to me from reading the docs). I can't find Chuck's e-mail, but it should be in the archives, and maybe Chuck himself will comment once again. I'm attaching his arecord script that he sent me, that might give you some idea of how to use arecord.
Greg

#!/bin/bash
trap "" SIGINT # ignore ^C
(trap - SIGINT # except in this subshell
arecord -d 7200 -q -r 22050 -f S16_LE -c1 /tmp/rec22km.wav )
echo wait...
if [ "$1" = "" ]; then
sox /tmp/rec22km.wav rec22km.wav >/dev/null 2>&1
echo rec22km.wav
(trap - SIGINT # except in this subshell
play rec22km.wav )
else
sox /tmp/rec22km.wav $1.wav >/dev/null 2>&1
echo $1.wav
(trap - SIGINT # except in this subshell
play $1.wav )
fi
rm /tmp/rec22km.wav > /dev/null 2>&1

Hi Igor,

The script I sent Greg, and which he resent, is not too
meaningful without a detailed commentary, and it is specific to
version 0.9.0beta11 of the alsa drivers. So if you just copy that
script it may or may not work for you.

In general you need to use a bunch of options with arecord in
addition to naming the file you want to create. You need to
specify the sampling rate you want to use, the sample size, the
file type, how many channels to create, and the duration of the
recording you want to make. How you do all those things will vary
somewhat depending on your version of alsa. The documentation is
pretty skimpy, but it is all there in the man page if you have
the patience to tease it out.

If you can tell us the alsa version you are using and show us the
command line you tried to use perhaps we can get more specific.

Hi

Glad that your requested the version number of the alsa driver as some of
the lines may produce interesting results.  I see that the -d (Duration) was
set at 2 hours, that's a lot of disk space.

Using alsa 09 beta 10 I use these lines:

arecord -d 1800 <filename>.wav

This will produce a 8 bit mono file of 14Mb of half an hour.

arecord -f cd -d 1800 <filename>.wav

Which will record a 16 bit stereo CD quality recording.  Can't remember the
disk space used for this half an hour recording.

A "arecord --help" will tell users what switches are available for their
particular version.  Providing the little indians don't get you, lol.

Re: aplay/arecord start-up error

[Igor Gueths]

Hi Chuck. My bad on the error thing. I just typed arecord --help and got
usage info, this means that the prog works. The only thing that threw me
off there was my little standard of just typing in program name and
expecting usage information. Kind of stupid of me that I didn't try that
yesterday, but again I was doing this at about 2:00 a.m smile!

Re: aplay/arecord start-up error

[Igor Gueths]

Hi
all. Now that I think about it, got another question. I got the alsa
drivers/lib/utils version 0.9.0beta12, but I couldn't figure out where the
drivers were placed. I am using beta 9 and using a start-up script that I
wrote that loads the apropriate module at boot time. In terms of beta 12,
I looked in /lib/modules/2.4.18/kernel/sound/acore. I looked in the isa
directory, considering that I have an isa-pnp card, and the driver for my
cs4236 wasn't present. With beta9, I just use modprobe to load the mods,
and everything works perfectly. Any ideas of where the installer may have
hidden those drivers lol! Thanks.  On Thu, 18 Apr 2002, 'Georgina' wrote:

Igor -

It is possible that the names of the drivers may have changed.
They used to be called "snd-card-xxxx" but at least in beta11
they are now called "snd-xxxx" without the "card" part.

Hi Chuck. But is their some specific dir where the drivers are placed? For example /lib/modules/2.4.18/misc? Thanks!

RE: aplay/arecord start-up error

[Watson, Keith]

Hi all,

Since we are posting arecord usage I thought my two cents might help some.

arecord -q -d 2820 -f cd -r44100 -c2 -I track1.raw track4.raw

I use this to record 47 minutes of, oh lets say a 4 track source, off a
standard tape deck. The point is that you can split the channels with the -I
switch, if you have a need.

Hi

Glad that your requested the version number of the alsa driver as some of
the lines may produce interesting results.  I see that the -d (Duration) was
set at 2 hours, that's a lot of disk space.

Using alsa 09 beta 10 I use these lines:

arecord -d 1800 <filename>.wav

This will produce a 8 bit mono file of 14Mb of half an hour.

arecord -f cd -d 1800 <filename>.wav

Which will record a 16 bit stereo CD quality recording.  Can't remember the
disk space used for this half an hour recording.

A "arecord --help" will tell users what switches are available for their
particular version.  Providing the little indians don't get you, lol.
