dont know if there is 'software-amplification' on line out, but i guess there is only a kind of reduction in volume if level is not 100%. igain and line-out on 100% should be a good-choice theoretically, but we recognized often bad results with low-end-cards and igain on 100%, dont know really why, but on production, means live recording and streaming sounds etc., i use to have it on 50% or lower. ____ joy _______________________________________________ Alsa-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/alsa-user
