Takashi Iwai	b7bbf87608	ALSA: ctxfi - Use native timer interrupt on emu20k1 emu20k1 has a native timer interrupt based on the audio clock, which is more accurate than the system timer (from the synchronization POV). This patch adds the code to handle this with multiple streams. The system timer is still used on emu20k2, and can be used also for emu20k1 easily by changing USE_SYSTEM_TIMER to 1 in cttimer.c.

ALSA: ctxfi - Use native timer interrupt on emu20k1

emu20k1 has a native timer interrupt based on the audio clock, which
is more accurate than the system timer (from the synchronization POV).
This patch adds the code to handle this with multiple streams.

The system timer is still used on emu20k2, and can be used also for
emu20k1 easily by changing USE_SYSTEM_TIMER to 1 in cttimer.c.
