i moved to mint two days ago, but before i faced the same problem with gutsy and i wasn't able to solve it.
Here it goes..
I install the OS and everything works very nice... except the sound card my realtek 268... i use a compal ifl90 barebone laptop
i followed this method in gutsy forums
Method E: Patch to add support for Realtek ALC268 Codec to Alsa 1.0.14
Does work: [WWW] Acer TravelMate 6292, Compal IFL90, MSI PR200
Does not work:
Support provided :
Internal speaker works
Headphones works (and internal speakers are automuted correctly)
External speaker works (and internal speakers are automuted correctly)
Internal mic doesn't seem to work...
External mic untested.
Procedure (See [WWW] #116326) :
Rebuild the linux-ubuntu-modules-2.6.22 packages after applying this [WWW] patch
Or use this already pacthed,ready to install, [WWW] linux-ubuntu-modules-2.6.22-14-generic_2.6.22-14.37.1_i386.deb.
Note: It only works with an up-to-date Gutsy.
Add the following line in /etc/modprobe.d/alsa-base:
options snd-hda-intel model=acer
Note: You can specify one of the following model : acer, toshiba, 3stack or auto Note 2: For MSI PR200, use model=targa-dig
but it still doesn't working
i someone could really help me to solve this i will be realy thanked.
