I've been using generated wav files for bench trigger testing for a long time -with success.
Now I managed to have an Asus Eee 900 laptop for tuning, and it seems it has a different soundcard. If I attach the ECU to the headphone output, the ECU jumps to fine rpm for 2-3secs then it loses rpm signal (sometimes with trigger error).
It is the case every time I disconnect and reconnect the audio cable. -I need to disconnect, it's not enough to stop and restart playing from software.
Other notebooks work flawlessly in the very same situation and cables, but this tiny one (eee 900) not.
It's sound is fine listening through an earphone but not for VEMS
Any ideas?
