[PlanetCCRMA] Unable to run alsaplayer

[Mark W. Knecht]

Hi,
   Thanks for the info. I'm making a little headway, but I'll probably post
something over to alsa to see about a bit more info:

1) The reason there were two sets of errors in the earlier post was because
we have two channels. For whatever reason, when I change the -f and -g
options, it only fixes the left hand channel. The right still has no sound,
and has the clicks.

2) If I turn on the -r option (real-time scheduling) then the clicks and the
messages go away, but I still get the error message for the right channel

   xmms does the same thing playing a *.ogg file I downloaded. I get audio
on the left, clicks on the right. I see no option for 'real-time scheduling'
on that program.

   I'm not as concerned about the clicks as I am about getting stereo for
now.

   We'll see what else I can find out.

Have a good evening & thanks,
Mark

Those are latency hits, welcome to the world of not so low latency :-)
Don't know what might be causing this... make sure the hard disks are
tuned and that the low latency patch is enabled (docs in the web pages,
see tuning).

List all the files contained in a package:
  rpm -q -l package-name
What to look for:
  things in /usr/share/man/*
  --> man pages, "man whatever" prints them.
  things in /usr/bin/*
  --> programs
  things in /usr/share/doc/*
  --> documentation
There are links to each software package in the application pages (it is
on the name of the package). Obviously I need to add some basic docs :-)
So much to add, so little time. Vorbis is a compression algorithm, I
believe oggenc is the encoder. The package includes a library that is used
by many other programs (for example xmms - which thanks to it can play
compressed ogg vorbis files).
