[timidity-talk] Timididy + Virmidi = no sound?

[Hedley R. <he...@he...>]

Hi all.

Ok I am pretty much at a loss here... but hopefully someone with a little
more linux midi experience can point me in the right direction.

The short problem statement: =A0aconnect doesn't appear to connect virmidi
ports to Timidity ports.

Using gentoo, 2.6.11 kernel. =A0All ALSA drivers and libraries are version=
=20
1.0.9.
Timidity is version 2.13.2.

It is probably worth mentioning that I have loaded the virmidi and intel8x0
cards in different orders (slots) and the same issues appeared. =A0Currently
the virmidi device is card 1, and intel8x0 (nforce3) is card 2.

only relevant output from dmesg:

May 12 16:07:11 hedleytop intel8x0_measure_ac97_clock: measured 49416 usecs
May 12 16:07:11 hedleytop intel8x0: clocking to 47439

I fire up the timidity soft synth:

Playing directly to Timidity works and sounds great. =A0Timidity runs
at about 50% processor utilization.

aplaymidi -p 128:0 /root/Necromancer.mid

Then I try to connect my virtmidi port and play through it.

aconnect 64:0 128:0
aplaymidi -p 64:0 /root/Necromancer.mid

Doesn't give any errors, appears to play, yet no sound! =A0Timidity only
uses about 5% processor this time. =A0Something apparently is happening,
but I have no idea what =3D) =A0It appears to behave the same when playing
to an unbound/unconnected virmidi port as well

("aplaymidi -p 64:0 /root/Necromancer.mid" - same effect)

for most everything else, but could help?)

Thanks for any help you can provide.
