[9fans] Audio and other questions

[john]

I've been playing around a bit with playing music nicely under
Plan 9, but I've run into a few problems.
First, while trying to play music over drawterm from home, the
audio output is very choppy and slow--I'm pretty sure this has
to do with the fact that streaming PCM data over a cable
connection is not a good idea. If I set up a cpu server here at home
that boots from that remote filesystem, I should be able to drawterm
to that and play music from there to avoid the streaming problems,
right?

madplay works fine for playing stuff when I'm on the LAN with
my CPU server, but I'd rather use 'juke' for the playlist and
music sorting capabilities. However, the map files are tedious, to
say the least, so I'd like to use Axel Belinfante's perl scripts to
generate the maps... but the perl installation seems to expect
a kfs filesystem. Can someone tell me how to install it on fossil?

Lastly, is anyone working on sound drivers for a Thinkpad T22? I'm
using one as a terminal, and besides the lack of audio capabilities
everything works great. I'm under the impression that the T22 is
one of the more compatible and widely used laptops, so I thought
maybe somebody would be trying to make a driver for it.

Thanks

yes, sending raw PCM over a cable modem is likely to be unenjoyable,
or at least spottily so. do the decoding as close to your audio device
as you're able. with drawterm, that pretty much means your cpu
server's got to be nearby, yes.

the perl install consists of two steps: perl.setup and replica/pull
/n/dist/perl. it should be obvious what change is needed to that first
script. for the replica file, compare to /dist/replica/network,
particularly clientmount, for how the default keep-up-to-date
mechanism deals with fossil. i *think* you should be able to just lift
clientmount wholesale, but i've not tried that. maybe i will now...

do you know what the audio device in the T22 is?

okay, well, i also needed to change these definitions:
	c=/n/boot/dist/replica
	clientroot=/n/boot
	clientproto=/n/boot/sys/src/cmd/perl/perl.proto
and that seems to work (except for two missing files which seem to
genuinely not be on the cd image).

joy. except now i have perl on my system.

Since I'm the only one who should be using it... I just
copied the /n/dist/386/bin/perl binary over to my bin/386
dir.

Got this part fixed, at least in part. I just set up a standalone CPU
server here at home, so I just run drawterm to there, import
my directory from the distant server, and play away. I guess if I had
this new CPU/auth server boot from the distant server's fossil, I wouldn't
even have to import my home dir. What would I do to have the server
automatically boot from a remote fileserver? (I'd like to unplug the
monitor and keyboard, so automatic is important)
Thanks

all you need is a nvram file and a plan9.ini
file that says nobootprompt=kernel.
