[linux-audio-user] Jack server outputs no sound

I download a test WAV file testing.wav. ALSA here seems to be working
nicely, as I can hear the test sound using aplay.

I try to do the same using jackd. I start it as:

$ jackstart -d alsa

And from another shell I do and get:

$ jack.play testing.wav
jack.play: sample rate of file not that of server

Let's assume this is correct. So I stop jackstart and run it again
like this:

$ jackstart -v -d alsa -r 11025 -S

Then jack.play doesn't give any error but I can hear no sound. Find
attached jackstart's stderr output.

This computer is a Dell Latitude D610 laptop with an Intel ICH6 AC'97
audio controller running Debian sid and a 2.6.15.2 kernel with
preemption enabled and the realtime module loaded. Summarizing, ALSA
outputs sound, but jackd through ALSA doesn't.

I got here since I noticed that fluidsynth played MIDI files using
ALSA but not using jackd. Then I discarded a fluidsynth issue.

Any ideas?

Cordially, Ismael
