A non-zero recidx means that the driver/applications can use it as a recording/input source since that particular dev capable of providing sound sources to be recorded. You cannot record anything from SOUND_MIXER_RECLEV since it doesn't provide sound of its own, unlike SOUND_MIXER_VOLUME/PHONEOUT/CD/etc. Make sense, right? -- Ariff Abdullah FreeBSD --Signature=_Sun__23_Apr_2006_01_33_18_+0800_8D98iVHSw3XS8qnv Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.3 (FreeBSD) iD8DBQFESmjhlr+deMUwTNoRAm1SAJ9D84hy9Hv4P7v1O0byEkVVwl17xACfZjTi Ih83cEuQiycVuTFPlw4Ay3c= =srq3 -----END PGP SIGNATURE----- --Signature=_Sun__23_Apr_2006_01_33_18_+0800_8D98iVHSw3XS8qnv--
