The results are a bit surprising. You may want to check out http://ubuntuforums.org/showthread.php?p=3D825101#post825101. It's strange for me that it seems like Mic Preamplifier seems to be always off for LINE1 channel. It's also a bit strange that a jack connected to MIC1 always outputs in mono when set as output, but maybe that's just how Acer engineers decided it should be. And the third interesting thing is that the user could not select Mic modes at all for LINE-OUT channel. Did I skip this part in the datasheet, or is it undocumented? Also, is there really a difference between Mic 50% and Mic 80%? Maybe it's enough to only make one of these modes available in the mixer if there's no big difference between them? Same goes for Headphone/Line=96Out modes. What airbuds did you mention previously (you said Headphone mode might be useful for them)? Is it those small headphones that one can put INTO their ear and then hear poor sound? :) I don't have them handy ATM, so I can't test if there's any difference between Line-Out and Headphones modes for them... regards, Rimas --------------enigDCFCD0802B1D968AF3CC65AB Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2.2 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFEHVL5AlYAh8azrv8RAg00AJ9b3k8z3sMw6GRdSh9dvYOty3yd3wCeLWO/ GheAQnCj/27abR8X7QFmRpc= =EGpE -----END PGP SIGNATURE----- --------------enigDCFCD0802B1D968AF3CC65AB-- ------------------------------------------------------- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.
