 PulseAudio doesn't work. When I tried playing an MP3 using MPlayer's pulse
 driver,
 choppy sound is heard.

 PulseAudio's output:

 '''W: main.c: This program is not intended to be run as root (unless
 --system is specified).'''

 '''N: module-alsa-sink.c: Disabling timer-based scheduling because high-
 resolution timers are not available from the kernel.'''

 '''N: module-alsa-source.c: Disabling timer-based scheduling because high-
 resolution timers are not available from the kernel.'''

 '''W: alsa-util.c: Device hw:0 doesn't support sample format s16le,
 changed to u8.'''

 '''E: module-alsa-sink.c: ALSA woke us up to write new data to the device,
 but there was actually nothing to write! Most likely this is an ALSA
 driver bug. Please report this issue to the PulseAudio developers.'''

 '''E: module-alsa-sink.c: ALSA woke us up to write new data to the device,
 but there was actually nothing to write! Most likely this is an ALSA
 driver bug. Please report this issue to the PulseAudio developers.'''

 (repeats more, lines trimmed)

 '''E: module-alsa-sink.c: snd_pcm_mmap_commit: Device or resource busy'''

 '''Bus error'''

 It might be caused by a ALSA driver and library mismatch.

 (Note: '''als100''' is the driver)

 The driver perfectly works, but probably due to kernel driver and library
 mismatch, the library doesn't
 get the apropriate response from the kernel.

 My ALSA driver works perfectly. I can play anything with any program.
 (xine, mplayer, etc.)

 I haven't installed the latest drivers - yet.
