Hello, Thanks for your prompt response!
> Perhaps, TiMidity++ ALSA sequencer interface has been running as a > system service (like this: timidity -Os -iA) on Debian Wheezy/Jessy. The default timidity-daemon that is run by debian has the following parameters: -B2,8 -Os -iAD > Please try out adding "-B2,8 -q0/0" options. The fragment size is > adjustable. The smaller number gives better real-time response. > Adding "-B2,9" might be a good idea. If I run the daemon with the parameters you've given: $ timidity -iA -B2,9 -q0/0 -Os --sequencer-ports=1 -EFresamp=1 Requested buffer size 4096, fragment size 2048 ALSA pcm 'default' set buffer size 30104, period size 15052 bytes TiMidity starting in ALSA server mode Opening sequencer port: 129:0 Requested buffer size 4096, fragment size 2048 ALSA pcm 'default' set buffer size 30104, period size 15052 bytes $ aplaymidi -p 129:0 filename.mid There's still jitter. Even setting the number of fragments to 'maximum' (or minimum) (-B0) doesn't seem to have any effect. I've played around with the audio buffer size (-q) as well. Setting a smaller buffer seems to make it somewhat better, but still not as it should be. However, I've noticed that my /etc/asound.conf might have something to do with it. I have the following set there: pcm.dmixer { type dmix ipc_key 2 #unique IPC key ipc_key_add_uid TRUE slave { pcm "hw:Intel" #period_time 0 #in useconds period_size 4096 #in bytes buffer_size 131072 #in bytes rate 48000 format S32_LE } bindings { 0 0 1 1 } hint { show on description "Default sink for multiple (resampled) streams." } } I resample everything to 48kHz by default, as for some reason 44.1 sounds really distorted on my integrated DAC. Could that have something to do with it? Kind regards, Bill Carson ------------------------------------------------------------------------------ Slashdot TV. Video for Nerds.
