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: aconnect doesn't appear to connect virmidi ports to Timidity ports. Using gentoo, 2.6.11 kernel. All ALSA drivers and libraries are version 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. Currently 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 May 12 16:07:33 hedleytop intel8x0_measure_ac97_clock: measured 49433 usecs May 12 16:07:33 hedleytop intel8x0: clocking to 47456 ---------------------------------------------------------------------- I fire up the timidity soft synth: /usr/bin/timidity -iA -B2,8 -Os -EFreverb=0 ---------------------------------------------------------------------- Listing of cards and devices available: bash-2.05b# cat /proc/asound/devices 1: : sequencer 11: [0- 3]: raw midi 10: [0- 2]: raw midi 9: [0- 1]: raw midi 8: [0- 0]: raw midi 0: [0- 0]: ctl 33: : timer 50: [1- 2]: digital audio playback 57: [1- 1]: digital audio capture 48: [1- 0]: digital audio playback 56: [1- 0]: digital audio capture 32: [1- 0]: ctl bash-2.05b# cat /proc/asound/cards 0 [VirMIDI ]: VirMIDI - VirMIDI Virtual MIDI Card 1 1 [nForce3 ]: NFORCE - NVidia nForce3 NVidia nForce3 with AD1981B at 0xe0002000, irq 11 bash-2.05b# aplay -l **** List of PLAYBACK Hardware Devices **** card 1: nForce3 [NVidia nForce3], device 0: Intel ICH [NVidia nForce3] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: nForce3 [NVidia nForce3], device 2: Intel ICH - IEC958 [NVidia nForce3 - IEC958] Subdevices: 1/1 Subdevice #0: subdevice #0 ---------------------------------------------------------------------- Input ports listed: bash-2.05b# aconnect -i client 0: 'System' [type=kernel] 0 'Timer ' 1 'Announce ' client 64: 'Virtual Raw MIDI 0-0' [type=kernel] 0 'VirMIDI 0-0 ' client 65: 'Virtual Raw MIDI 0-1' [type=kernel] 0 'VirMIDI 0-1 ' client 66: 'Virtual Raw MIDI 0-2' [type=kernel] 0 'VirMIDI 0-2 ' client 67: 'Virtual Raw MIDI 0-3' [type=kernel] 0 'VirMIDI 0-3 ' ---------------------------------------------------------------------- Output ports: bash-2.05b# aconnect -o client 64: 'Virtual Raw MIDI 0-0' [type=kernel] 0 'VirMIDI 0-0 ' client 65: 'Virtual Raw MIDI 0-1' [type=kernel] 0 'VirMIDI 0-1 ' client 66: 'Virtual Raw MIDI 0-2' [type=kernel] 0 'VirMIDI 0-2 ' client 67: 'Virtual Raw MIDI 0-3' [type=kernel] 0 'VirMIDI 0-3 ' client 128: 'TiMidity' [type=user] 0 'TiMidity port 0 ' 1 'TiMidity port 1 ' 2 'TiMidity port 2 ' 3 'TiMidity port 3 ' ---------------------------------------------------------------------- Playing directly to Timidity works and sounds great. Timidity 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! Timidity only uses about 5% processor this time. Something apparently is happening, but I have no idea what =) It appears to behave the same when playing to an unbound/unconnected virmidi port as well ("aplaymidi -p 64:0 /root/Necromancer.mid" - same effect) ---------------------------------------------------------------------- my .asoundrc (not sure if this is helpful, as sound pretty much works for most everything else, but could help?) #/etc/asound.conf start: # define the default device pcm.!default { type plug slave.pcm "dmixer" } # define the "dsp0" device pcm.dsp0 { type plug slave.pcm "dmixer" } # define the slave pcm dmixer device pcm.dmixer { type dmix ipc_key 1024 slave { pcm "hw:1,0" period_time 0 period_size 1024 buffer_size 8192 rate 44100 } bindings { 0 0 1 1 } } # define the "dsnooped" device for capturing pcm.dsnooped { type dsnoop ipc_key 1024 slave { pcm "hw:1,0" period_time 0 period_size 1024 buffer_size 8192 rate 44100 } } # define the "duplex" device for full duplex operations pcm.duplex { type asym playback.pcm "dmixer" capture.pcm "dsnooped" } # define the "dsp1" device and slave "duplex" for full duplex operations pcm.dsp1 { type plug slave.pcm "duplex" } # define the "dmixer" control device ctl.dmixer { type hw card 1 } # define the "dsp2" for folks who don't want to play friendly with dmix pcm.dsp2 { type hw card 0 } #end.
