Hey All, While trying to record from the line in on a Vortex 2 card (either directly to file, or while being shoutcasted by blackice) using the aureal drivers in the ports, there is a lot of distortion. Almost like there is a feedback loop somewhere within the mixer. I am using an Aureal Vortex 2 card with FreeBSD 4.5-RELEASE, and the latest version of the aureal drivers. My mixer settings are as follows: Mixer vol is currently set to 0:0 Mixer bass is currently set to 0:0 Mixer treble is currently set to 0:0 Mixer pcm is currently set to 0:0 Mixer speaker is currently set to 0:0 Mixer line is currently set to 70:70 Mixer mic is currently set to 0:0 Mixer cd is currently set to 0:0 Mixer rec is currently set to 35:35 Mixer ogain is currently set to 0:0 Mixer line1 is currently set to 0:0 Mixer phin is currently set to 0:0 Mixer video is currently set to 0:0 "Line" is the only thing set up to record. Everything else is set to playback. You can listen to the stream here (56kbps) - http://213.80.36.207:9002/ using shoutcast, or if you need 28kbps - http://213.80.36.207:9000/. The stream is a test stream, of a local radio station (Glasgow, Scotland). The radio is plugged directly in to the sound card and has a good, clean, strong input signal (but not strong enough to cause these distortions - well within normal levels). Traditionally, I'm a server admin. I admit I haven't really touched the multimedia side of FreeBSD before, but this has become a requirement recently.. So forgive me if I'm not sending important diagnostic information etc in this email.. Or if I'm asking stupid questions.. I would appreciate any help a LOT!
