I installed in my C4 version of BB, my own built Angstrom kernel using
OE. It is 2.6.29 kernel. After loading the kernel, I set out to
perform the kernel based audio in test. When I type "arecord ....."
command, it says "-sh: arecord command not found"....I tried to look
up similar posts in the Beagleboard group, but could not get a
concrete answer......
I am not familiar with this, but in general if that program is a part of the distribution, then maybe there is an issue with the path. Since you say you built your own kernel, did you also build all the applications and other related modules (so you get arecord)? If you did build it, locate the executable using the find command and run it. If you are using busybox, I doubt if this will come up by default.
I ve searched for new intel atom pcs and they include box + lcd + board all includes with full working laptop costs ~250$ like but i dont know for unit costs of beagleboard.
150$ for single card is expensive , how effects mass buying of products ?
I've seen more cheaper cards for industrial applications.
Beagleboard is only kit or we can buy mass with cheaper costs ?
Sorry for my english.
We need cheap solution board for industry like beagleboard.
But if buying mass doesnt effect cost of product makes this product useless really against other solutions.
Maybe, look at Palm Pre. It sells for $149 from Sprint and uses a 3530 and has lot of useful peripherals. All you need is to figure out how to load your own BL and OS onto it.
Ok, jokes apart, I seriously doubt if you can get a dev board as feature rich as Beagle for that price. You were comparing it with commercial products like netbooks that are mass produced and hence cost less. If you intend to purchase in bulk, you might have to approach an oem.

Please respond........I am waiting for inputs from you........
As in your original message,
"-sh: arecord command not found"
means, that `arecord` is not installed on your system or not in your
path.
I suspect the former. `arecord` is a utility provided by the ALSA
project [1]. Please make sure you have it installed. I do not see an
extra package for it on [2], but `alsa-utils-aplay` [3] seems to include
it too (»play (and record) sound files via ALSA«) so please verify if it
is installed on your system and if not install it using `opkg`.
Thanks a lot for your pointers. I downloaded the link [3] that you
provided for armv7 architecture, put it in SD card, then installed
using opkg command on the beagle serial console, and it worked
perfectly........But during installation it threw an error that for
installing this utility, it needed libgcc 4.3.3 or greater and I
downloaded that too from the repository and opkg-ed
it.........Initially only aplay command worked, but arecord did
not.......I referred to the thread http://groups.google.com/group/beagleboard/browse_thread/thread/9ca5654cf09035e7/8646fcda682ef97a?show_docid=8646fcda682ef97a
and that also got solved.......
Now I am able to record and play it back perfectly.........
I can play audio, but if I play recorded audio, it is static noise. I
looked at audio
file. It seems recorded but one of two bytes is always either 0xFF or
0xFE
