Stefan,
Try using
-p128 -n2, and tell us whether you can't
notice any aural difference, let alone if you can
ignore a XRUN storm =:)
Ok, if it can get 2x128 that's quite tempting: I'd
always assumed the crackling was a USB1 thing... I'd
be grateful if you could give me a little help with it
though please. I'm running PlanetCCRMA Fedora Core 1
at the moment. From your page I gather that I need
jack-0.99.35.3usx2y.tar.gz. Am I right in thinking
that the 'linux' section is kernel patches? Is there
no way I can use this with the CCRMA 2.4.26-1 kernel
(with low latency, givecaps, preempt etc)?
You can possibly try building from current alsa-kernel/alsa-driver cvs,
where the new alsa module code lives.
I guess you'll have to install the Planet's kernel-source package and then
follow the alsa-driver installation instructions. Please do us a favor and
ask for some advice on the planetccrma list, would you?
For building from jack-0.99.35.3usx2y.tar.gz, you may go by building your
own RPMs, how's that? However, you'll have to change the package name from
"jack" into "jack-audio-connection-kit", if you want to avoid trouble
with
your planetccrma installation.
These are summary instructions, from the command line (do all as root):
# tar -zxf jack-0.99.35.3usx2y.tar.gz
# cd jack-0.99.35.3usx2y
Edit configure.ac, and change the following line
AM_INIT_AUTOMAKE(jack,${JACK_VERSION}.3usx2y)
to
AM_INIT_AUTOMAKE(jack-audio-connection-kit,${JACK_VERSION}.3usx2y)
then,
# aclocal && autoheader && automake && autoconf
# ./configure --enable-capabilities && make && make dist
# cp jack-audio-connection-kit-0.99.35.3usx2y.tar.gz \
/usr/src/redhat/SOURCES/
# rpmbuild -bb jack.spec
Hopefully, you'll find your freshly made RPMs, under the directory
/usr/src/redhat/RPMS/i386, ready for installation (rpm -Uvh ...):
jack-audio-connection-kit-0.99.35.3usx2y-1.i386.rpm
jack-audio-connection-kit-devel-0.99.35.3usx2y-1.i386.rpm
jack-audio-connection-kit-example-clients-0.99.35.3usx2y-1.i386.rpm
Please note that the packages will replace the current installed ones,
AFAICT.
... the new
hwdep pcm (aka "rawusb") interface
available on the
sand-usb-usx2y alsa kernel module.
Sorry I don't understand this at all. I can't find
anything about sand-usb-usx2y, but do you mean if I
installed latest alsa I could use sand-usb-usx2y in
place of snd-usb-audio in modules.conf?
Oops, that was my typo, It's the same old "snd-usb-usx2y" I was referring
to, sorry.
Bye.
