I have just today started using CCRMA. I installed the distribution
using your installation notes (installing fedora 10, yum update,
adding ccrma repo, installing ccrma).

According to lspci, my soundcard is:

00:06.0 Multimedia audio controller: VIA Technologies Inc. VT1720/24
[Envy24PT/HT] PCI Multi-Channel Audio Controller (rev 01)

Now, when I start jack using "jackd -R -dalsa", every few minutes I
get the error:

ALSA: poll time out, polled for 31999959 usecs
JackAudioDriver::ProcessAsync: read error, skip cycle

And when in qjackctl I try to connect audio system input to output, it
doesn't do anything, just in the shell window in which I started jack:

JackGraphManager::Connect already connected port_src = 1 port_dst = 3
JackGraphManager::Connect already connected port_src = 2 port_dst = 4

which seems strange to me, since it doesn't show the connections in

cat /proc/asound/cards says:

0 [ICE1724        ]: ICE1724 - ICEnsemble ICE1724
                      ICEnsemble ICE1724 at 0xe800, irq 17

I hope those error messages can give you a hint about what is
wrong. If there is any other output I can give you, please help..

Thanks in advance
