Further to my previous email on this subject I have been able to
independently confirm that the "mono" control does indeed control the
internal speaker in these C20x-series laptops.
Valentin: if you can, could you please try the following patch (against
alsa-driver 1.0.13 in alsa-driver-1.0.13/alsa-kernel/pci/hda/)? With it:
* you will be presented with the "Acer" model variant without having
to specify "model=acer" when loading the snd-intel-hda modules.
* there will be new alsamixer controls for a "mono speaker" which is
what the C20x series appears to be equipped with.
If all is well, please see if the new "mono speaker" controls affect the
internal speaker.
Note that this patch will unconditionally add the "mono speaker" controls
to all configurations which utilise the "Acer" ALC260 model. I've named
them "Mono Speaker ..." on the basis that one would expect them to only
have an effect if one has a single mono speaker. On first thoughts it seems
silly to define a whole new model just to add two controls, but the presence
of "non-working" controls on laptops which don't have the mono speaker
may confuse end users.
What is the general consensus of the list? Should I define a new model for
these C20x tablet PCs or is the unconditional addition of "mono speaker"
controls to the existing "acer" model acceptable?
Regards
jonathan
