|
|
Hi everyone, I have this ASUS eee PC and it has only one jack slot. The idea is that the slot should be shared between headphones and microphone - system should either autodetect the device plugged in or let the user decide. My friend has the same model running windows 7 and everytime something is plugged in, there is a dialog box asking whether it's a microphone or headphones or whatever. My Gentoo linux always uses the slot for headphones, nomatter what I tried I wasn't able to record anything with any sort of device plugged in. So that's basically the problem.
Technical details:
Sound is working fine, there is an integrated microphone, which also works fine, but that's not exactly what I want
Soundcard - HDA Intel
Chip - Realtek ALC269VB
Kernel has the right sound [/u]drivers compiled into it - kinda weird, should I recompile them as modules? |

I know you're looking for an answer, which this is not (sorry), but that sounds like a really bad design. Inputs and outputs should always be separate connections.
Actually, I can directly answer your question: it doesn't matter whether you use in-kernel or modules. Per function, the result will be the same. However, I always encourage people to compile sound and video drivers as modules. This makes it easier to troubleshoot by providing the ability to load or unload modules without having to reboot. _________________ decibel Linux: https://decibellinux.org

Have you checked in alsamixer for a switch to toggle it between input/output? |

I've checked for such a thing in alsamixer, there wasn't. Any other ideas? |

It has a pretty weird range of software-controlled stuff and usually nowhere else to put it. I've got an old Vortex II that stuffs an entire graphic EQ (and its level monitors) into volume controls.

You'll probably get a better answer faster on the ALSA mailing lists. It's possible they just don't know about this hardware yet. |
