Hi !

You seem to have problems with your network setup.

First try

ping localhost

This should show you how the connection to your localhost is working. If this is not working, your network loopback device is misconfigured.

After doing

/sbin/ifconfig

You should see a line like

lo Link encap: Local Loopback ....... .....

If it isnŽt there, your loopback device isnŽt configured at all. Pd connects its User interface and server through TCP/IP. You need a working loopback device if you want to run Pd.

You could also look into /etc/hosts, where there should be an entry like: 127.0.0.1 localhost

And last but not least, the command

/sbin/route

should show you something like:

Destination Gateway Genmask localnet * 255.255.255.0 ....

unfortunately I am not using Redhat, so someone more familiar with the Redhat setup can probably give you more information what is going wrong. If, for example, "ping localhost" doesnŽt work, you might ask on a Rehat list what is going wrong.

I just installed PD 0.24 under Redhat Linux 5.2 on a Pentium 333. I'm running KDE for a window manager.

When I try to run PD I get the message:

Connecting stream socket: network is unreachable 101

Then nothing. I hit Ctrl-C to get back to the bash prompt. I'm relatively green to Linux. What do I need to do?

Thanks, Elliot Anderson

Hi all,

Funny thing I noticed.

When I run pd with the default settings (-r 44100 -ada) no gem (still.....) it eats up about 50% of the cpu cycles. Just when it's idle, no patches open, audio off.

What kind of sounddriver do you have installed ? I guess you use the commercial OSS driver. Unluckily full duplex doesnŽt work with the commercial version. (Although the API is fully compatible to the free version :). .. and it really makes me wonder where it burns up the CPU cycles.

In the case of the same sampling rate but running in -dac mode it takes about 1% when having something like one osc~.

I can run it fine in the -ada mode at -r 22050. Even a complex patch doesn't take much cpu (well, within reason).

Any ideas about this behaviour?

Maybe the sounddriver has problems with the fragment size and fragment number . (Note, this is an internal detail of a sounddriver)

There are two hidden command flags for pd, with which you can exeriment.

-frags <num> and -fragsize <num>

the parameter to -frags normally is the same as the "advance" which is displayed during startup. fragsize is set to 8 by default (this makes up 64 audio samples).

Try to set the fragsize to 9,10 or even 11, and look what happens e.g.

pd -fragsize 10

PS: if you have problems compiling Gem, just send my the output of compile and make, then I can try to figure out what is going on there.

which OSS ? free : commercial;

RedHat 5.2
