When 2.6.15 was released, we had ALSA 1.0.11rc2. I understand. Still, 2.6.15 has 1.0.10rc3 and current alsa "stable" does not work out of the box with it (at least for some of the cards and in my tests - hmmm, maybe this only happens when running with the -rt patches?). There's one additional tiny patch needed in alsa 1.0.10 if you want snd-rtctimer to be detected by configure and subsequently built under 2.6.15+: ======== alsa-driver-1.0.10/configure~ 2005-11-16 09:41:17.000000000 -0500 +++ alsa-driver-1.0.10/configure 2006-03-06 20:48:03.152744160 -0500 @@ -8260,7 +8260,7 @@ echo "$as_me:$LINENO: checking for RTC callback support in kernel" >&5 echo $ECHO_N "checking for RTC callback support in kernel... $ECHO_C" >&6 rtcsup="" -if test "$kversion.$kpatchlevel" = "2.6" -a "$kpatchlevel" -ge 15; then +if test "$kversion.$kpatchlevel" = "2.6" -a "$ksublevel" -ge 15; then ac_save_CFLAGS="$CFLAGS" ac_save_CC=$CC CFLAGS="$KERNEL_CHECK_CFLAGS" ======== -- Fernando - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
