No guarantees, YMMV. Thanks for the tip. It sounds promising, but I don't get it to work properly. I've started jackd with: jackd -Rv -d alsa -d default -p 512 -n 3 -r 44100 Everything runs fine (no xruns). Then I start ecasound as you mentioned, which after a 10 seconds or so says: - [ Engine init - Driver start ] ------------------------------------------- (eca-engine) Using realtime-scheduling (SCHED_FIFO). (audioio-alsa) warning! playback overrun - samples lost! Break was at least 6.66 ms long. zombified - calling shutdown handler - [ Controller/Batch processing finished ] --------------------------------- - [ Engine exiting ] ------------------------------------------------------- (eca-controller) Disconnecting chainsetup: "command-line-setup". (audioio-jack-manager) Connection closed! - [ Chainsetup disconnected ] ---------------------------------------------- (audioio-alsa) WARNING! While reading from ALSA-pcm device C0D0, there were 1 overruns. At the same time I the jackd responds with: subgraph starting at ecasound timed out (subgraph_wait_fd=9, status = 0, state = Running) at 618674458 client waiting on 9 took 12732 usecs, status = 1 sig = 618661179 awa = 618661187 fin = 0 dur=0 client ecasound error: awake_at = 618661187 state = 2 timed_out = 2 client failure: client ecasound state = Running errors = 1 *&*&*&*&** senor ecasound - you are a ZOMBIE ++ jack_rechain_graph(): client alsa_pcm: internal client, execution_order=0. -- jack_rechain_graph() **** alsa_pcm: xrun of at least 1.152 msecs load = 1.3967 max usecs: 39.000, spare = 11570.000 load = 0.8965 max usecs: 46.000, spare = 11563.000 load = 0.5774 max usecs: 30.000, spare = 11579.000 removing failed client ecasound state = Not triggered errors = 0 adios senor ecasound ++ jack_rechain_graph(): client alsa_pcm: internal client, execution_order=0. -- jack_rechain_graph() Maybe I have to fiddle around with the settings of jackd and ecasound, however I have no idea what to change to what. best, Jeroen -- Kile - an Integrated LaTeX Environment for KDE http://kile.sourceforge.net
