IDT/Sigmatel codecs ------------------- * Analog Loopback This control enables/disables the analog-loopback circuit. This appears only when "loopback" is set to true in a codec hint (see HD-Audio.txt). Note that on some codecs the analog-loopback and the normal PCM playback are exclusive, i.e. when this is on, you won't hear any PCM stream. * Swap Center/LFE Swaps the center and LFE channel order. Normally, the left corresponds to the center and the right to the LFE. When this is ON, the left to the LFE and the right to the center. * Headphone as Line Out When this control is ON, treat the headphone jacks as line-out jacks. That is, the headphone won't auto-mute the other line-outs, and no HP-amp is set to the pins. * Mic Jack Mode, Line Jack Mode, etc These enum controls the direction and the bias of the input jack pins. Depending on the jack type, it can set as "Mic In" and "Line In", for determining the input bias, or it can be set to "Line Out" when the pin is a multi-I/O jack for surround channels. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1078924 Title: [Latitude E6520, IDT 92HD90BXX, Black Mic, Left] No sound at all To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1078924/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
