ALSA works better now after the update but pianobar on raspbian still stutters even under no load (30%).

Using screen I got it to crash just by switching from bash:0 to bash:1 with this output to dmesg

[ 675.740026] vcos: [3020]: bcm2835_audio_close:702 bcm2835_audio_close: failed on waiting for event (status=10)

I don't believe I can run pianobar without a login.Can you find any other audio player with the same symptoms?

Maybe I am having the same trouble with stutter as the ratherDashing. Running SqeueezePlay on the latest raspbian 18-09-2012 with the default asound.conf causes stutter every now and then. Looking at syslog when the stutter occurs I can see that the following entries is logged:

Is this still an issue with latest (rpi-update) kernel/firmware?
