Public bug reported:
On my Lenovo D10 when reporting the sound hardware, among others, my
"Internal Audio" is shown. When selecting this for sound output I hear
music via my attached speakers and the internal PC speaker. I had the
same problem in 9.04 but via sound preferences was able to switch off
the PC speaker as a workaround. This option is no longer available, as
far as I can see.
I've been playing around with the "old" blacklisting hints for the
modules but no success so far. They're blacklisted by default, but
enabling them at least doesn't make a difference in the options for
sound preferences.
