[linux-audio-user] realtime problems

Hi I just installed xubuntu 6.06 on my T41 laptop. When I start jack like this: "jackstart -R -d alsa -p 64" I get: jackstart: cannot get realtime capabilities, current capabilities are: =ep cap_setpcap-e probably running under a kernel with capabilities disabled, a suitable kernel would have printed something like "=eip" This is both with the stock kernel (2.6.15) and a 2.6.17 patched with http://people.redhat.com/mingo/realtime-preempt/ Here's something from my .config: atte@ajstrup:~$ grep PREEMPT /usr/src/linux/.config # CONFIG_PREEMPT_NONE is not set # CONFIG_PREEMPT_VOLUNTARY is not set # CONFIG_PREEMPT_DESKTOP is not set CONFIG_PREEMPT_RT=y CONFIG_PREEMPT=y CONFIG_PREEMPT_SOFTIRQS=y CONFIG_PREEMPT_HARDIRQS=y CONFIG_PREEMPT_BKL=y CONFIG_PREEMPT_RCU=y # CONFIG_DEBUG_PREEMPT is not set # CONFIG_CRITICAL_PREEMPT_TIMING is not set Another thing: Supposed I get the realtime kernel running, one of my usb keyboards (evolution mk-449c) is not recognized (tried both vanilla 2.6.17 and with the patch applied + the 2.6.17.7 w/wout patch). When I plug it in I get this in dmesg: [ 500.792000] usb 2-2.1: new full speed USB device using uhci_hcd and address 4 [ 500.916000] usb 2-2.1: no configuration chosen from 1 choice Needless to say, my alsa configuration is exactly the same with all kernels, here's my /etc/modprobe.d/alsa-base: atte@ajstrup:~$ cat /etc/modprobe.d/alsa-base # autoloader aliases install sound-slot-0 modprobe snd-card-0 install sound-slot-1 modprobe snd-card-1 install sound-slot-2 modprobe snd-card-2 install sound-slot-3 modprobe snd-card-3 install sound-slot-4 modprobe snd-card-4 install sound-slot-5 modprobe snd-card-5 install sound-slot-6 modprobe snd-card-6 install sound-slot-7 modprobe snd-card-7 # Cause optional modules to be loaded above generic modules install snd modprobe --ignore-install snd $CMDLINE_OPTS && { modprobe -Qb snd-ioctl32 ; : ; } install snd-pcm modprobe --ignore-install snd-pcm $CMDLINE_OPTS && { modprobe -Qb snd-pcm-oss ; : ; } install snd-mixer modprobe --ignore-install snd-mixer $CMDLINE_OPTS && { modprobe -Qb snd-mixer-oss ; : ; } install snd-seq modprobe --ignore-install snd-seq $CMDLINE_OPTS && { modprobe -Qba snd-seq-midi snd-seq-oss ; : ; } # Cause optional modules to be loaded above sound card driver modules install snd-emu10k1 modprobe --ignore-install snd-emu10k1 $CMDLINE_OPTS && { modprobe -Qb snd-emu10k1-synth ; } install snd-via82xx modprobe --ignore-install snd-via82xx $CMDLINE_OPTS && { modprobe -Qb snd-seq ; } # Load saa7134-alsa instead of saa7134 (which gets dragged in by it anyway) install saa7134 modprobe --ignore-install saa7134 $CMDLINE_OPTS && { modprobe -Qb saa7134-alsa ; : ; } # Prevent abnormal drivers from grabbing index 0 options snd-bt87x index=-2 options snd-atiixp-modem index=-2 options snd-intel8x0m index=-2 options snd-via82xx-modem index=-2 # i810 alias sound-service-0-0 snd-mixer-oss alias sound-service-0-1 snd-seq-oss alias sound-service-0-3 snd-pcm-oss alias sound-service-0-8 snd-seq-oss alias sound-service-0-12 snd-pcm-oss alias snd-card-0 snd-intel8x0 alias sound-slot-0 snd-card-0 # ua-1a alias sound-service-1-0 snd-mixer-oss alias sound-service-1-3 snd-pcm-oss alias sound-service-1-8 snd-seq-oss alias sound-service-1-12 snd-pcm-oss alias snd-card-1 snd-usb-audio alias sound-slot-1 snd-card-1 #evolution 1 alias snd-card-2 snd-usb-audio alias sound-slot-2 snd-card-2 #evolution 2 alias snd-card-3 snd-usb-audio alias sound-slot-3 snd-card-3 #evolution 2 alias snd-card-4 snd-usb-audio alias sound-slot-4 snd-card-4 options snd-intel8x0 index=0 options snd-usb-audio index=1,2,3,4 vid=0x0582,0x0a4d,0x0a4d,0x0a4d pid=0x0018,0x008e,0x008e,0x008f nrpacks=1 -- peace, love & harmony Atte
