however.. - it may be a rather large switch statement to deal with all the various type of inputs... that ioctl accepts...
Anyone else want to add thoughts on that..

At urging of those who feel pear.dev is the wrong place to propose PECL packages, I'm repeating my proposal here:
-------------------------------------------------------------------
I'd like to propose two PECL extensions:
1) linux_oss http://frankenbox.alphaweb.net/test/linux_oss-0.1.tgz
Description: Bindings for the Linux Open Sound System API.
Functions: linux_oss_buffer() : Setup DSP buffer on /dev/dsp or similar device linux_oss_channels() : Set DSP to process number of channels (mono vs. stereo) linux_oss_rate() : Set sampling rate on DSP device linux_oss_format() : Set sample encoding 8/16 bit, signed/unsigned, big/little endian linux_oss_mixer_query() : Probe capabilities of mixer linux_oss_mixer_vol() : Get/Set volume on mixer channel linux_oss_mixer_source() : Get/Set recording source
Purpose: Control sound I/O on linux systems. Yes, this is platform specific, but sound is a platform specific thing. I'll propose Windows sound system bindings later, and ultimately bindings for Solaris and BSD as I research them.
Requirements: PHP >= 4.3.0, Linux w/ OSS kernel module and headers
2) oggvorbis http://frankenbox.alphaweb.net/test/oggvorbis-0.1.tgz
Description: OGG/Vorbis fopen wrapper.
ogg:// write - Encode PCM audio to OGG/Vorbis compressed audio.
ogg:// read - Decode OGG/Vorbis compressed audio to PCM.
Example Usage: .ogg player
<?php dl('linux_oss.so'); dl('oggvorbis.so');
$input = fopen('ogg://mymusic.ogg', 'r'); $oggdata = stream_get_meta_data($input);
/* Chained OGGs will be added as subsequent numericly indexed subarrays of wrapper_data */ $songdata = $oggdata['wrapper_data'][0];
$output = fopen('/dev/dsp', 'w'); linux_oss_buffer($output, 8192); linux_oss_channels($output, $songdata['channels']); /* AFMT_S16_LE is the default output mode of ogg:// wrapper. It can also be set to encodings listed above via a context option. */ linux_oss_format($output, AFMT_S16_LE); linux_oss_rate($output, $songdata['rate']);
$mixer = fopen('/dev/mixer', 'w');
/* Master Volume L / R */ linux_oss_mixer_vol($mixer, MIXER_VOLUME, 100, 100);
/* DSP Output Volume L / R */ linux_oss_mixer_vol($mixer, MIXER_PCM, 100, 100);
stream_copy_to_stream($input, $output);
fclose($mixer); fclose($output); fclose($intput); ?>
Requirements: PHP >= 4.3.0, libogg, libvorbis (both governed by BSD style licenses)
