I have just discovered a minor logic inversion bug in
aplay/arecord --list-pcms functionality.
Basically, executing "aplay --list-pcms" lists all devices capable of
capture and executing "arecord --list-pcms" lists all devices capable
of playback.

By doing this we move them from the .data section to .rodata setion,
or from .data.rel to .data.rel.ro.
The .rodata section is mapped directly from the on-disk file, which is
always a save, while .data.rel.ro is mapped directly when using
prelink, which is a save in a lot of cases.

This way the compiler can assume more information about their
interface for optimisation.

In some cases (HDA audio) the ring buffer position values returned
from alsa-lib are inaccurate. The added --test-position option will
print suspicious values.

Added the support of stereo VU-meter.
Enabled via -Vs option.
The new option, -V, can be used to enable the VU-meter. Now
VU-meter can be enabled even without -vv.
WAV files with more than 2 channels or with more than 16 bits per samples
can be saved with "extensible format" chunk
(see http://msdn2.microsoft.com/en-us/library/ms713496(VS.85).aspx).
For instance, sox, when converting data to 24- or 32-bits per sample format
uses this format, and aplay was unable to play such file. Now the problem
is solved :-)

This patch modifies aplay/arecord to support playing/capturing IEEE float
32-bit WAV files. Tested on HDA hardware in both stereo and multi-channel
modes. Added the WAV file constant for Dolby AC-3 S/PDIF passthrough to
formats.h for future use when AC-3 passthrough is better supported.

snd_pcm_drain() doesn't block when running with O_NONBLOCK.
Reset the non-blocking mode before calling snd_pcm_drain() properly
(and restore again for any further operations).
- remove unused static declaration
- fix double close in signal handler
- fix NULL reference
- fix max file size to stdout with non-raw format
- code clean up

This patch will split files in chunks of aprox. 2GB in the interleaved
recording mode of arecord. This is meant to overcome the 2GB filesize
limit of .wav files, which is easily reached when recording multiple
channels.
From: Dirk Jagdmann <doj@cubic.org>
This patch adds an alternative peak meter for aplay/arecord which is
enabled via three "-v" command line arguments. This new mode differs
from the old in a larger meter, no linefeeds for every meter update and
a static maximum peak (for 1s).
This patch converts hyphens to minus signs in the man pages (for options,
emails, or command line examples).
This patch also closes one font modifier in iecset.1.

- don't parse -X option because such an option doesn't exist
- allow argument for --sleep-min option
- fix handling of .voc magic string
- fix handling of .voc files on big-endian machines
- remove superfluous "size" parameter from check_wavefile_space macro
- reallocate buffer only if needed in check_wavefile_space
- fix playback of >2GB .wav files
- skip over padding bytes in .wav files
- fix memory leak when playing .voc silence blocks
- fix file length when recording >2GB .wav files
- fix recording of >4GB files
arecord doesn't record if you don't indicate the time limit
The problem happens when the Wave-file is checked for it being even.
I have tried with the next change in aplay.c and it seems to work fine.
- add a "Press Escape to quit" string to alsamixer's title, some uses
couldn't figure out how to exit the program (Debian Bug#178393).
- hide the cursor, which was missplaced and wasn't goodlooking anyway
(Debian Bug#81169).
- remove trailing spaces from amixer's output (Debian Bug#177518).
- don't ignore second -l/-L flags in aplay (Debian Bug#177521).
