Ouhm, a pity. Guess that it took ~11 years for someone to notice is an indicator of the percentage of users using the digital in ;-) You could plug a cable from the output to the input for testing, no? As I=92m not familiar with the ALSA driver I guess I would rather spend a whole month or so trying to copy and paste something together, =85 Ren=E9 -- = ExactCODE GmbH, Lietzenburger Str. 42, DE-10789 Berlin DE Legal: Amtsgericht Berlin (Charlottenburg) HRB 105123B, Tax-ID#: DE2516= 02478 Managing Director: Ren=E9 Rebe http://exactcode.com | http://exactscan.com | http://ocrkit.com | http://t= 2-project.org | http://rene.rebe.de
