[alsa-devel] Intel ICH7/Realtek ALC262 on MSI MS-7290 (Crystal 945)

[Tobin Davis]

Sorry for not getting back sooner.   Could you try alsa-1.0.16rc2 with
the following configuration:

        ./configure --with-cards=hda-intel --with-debug=detect && make
        && sudo make install

After it is installed, type "dmesg" and look for the alsa output
(line-outs, speakers, etc).  Copy that into an email and send it to me,
please.
