Hi all, I've noticed my laptop (Panasonic CF-53; Realtek ALC269VC) which has stereo headphone output and microphone input sockets, can have its microphone input switched to a stereo line input mode. This is handy indeed as I often use an analogue audio input (various tasks… sometimes its interfacing to a radio transceiver for digital modes, sometimes it's capturing audio off a cassette tape or vinyl record so I don't lose access to said audio when player bites the dust). Prior to this I was using a USB audio device (C-Media CM6317-based) which was ripped out of a broken AU$30 USB record player, and this started misbehaving yesterday… going through `pavucontrol` I was able to switch the on-board sound card so that the mono microphone input was now a stereo line input (at the cost of audio out going via HDMI, thankfully I'm using USB audio for monitoring anyway). Only quirk is that left and right channels were swapped -- easy enough to fix in hardware (audio source here uses RCA jacks, so just swap them over). I don't see anything obvious in `alsamixer`, and so far my searches on the topic have turned up nought. What voodoo is PulseAudio doing to achieve this? -- Stuart Longland (aka Redhatter, VK4MSL) I haven't lost my mind... ...it's backed up on a tape somewhere. _______________________________________________ Alsa-user mailing list Alsa-user@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/alsa-user
