From: Hans de Goede <hdegoede@xxxxxxxxxx> [ Upstream commit c8b78f24c1247b7bd0882885c672d9dec5800bc6 ] The MPMAN MPWIN895CL tablet almost fully works with out default settings. The only problem is that it has only 1 speaker so any sounds only playing on the right channel get lost. Add a quirk for this model using the default settings + MONO_SPEAKER.
