Hi Takashi,
I have run into the issue that OSS emulation layer provides less controls than the alsa mixer. One specific problem is the OSS Speaker control is not properly mapped on all drivers (among others the wss/cs4236 family) due to the fact that the speaker input/output is called "Mono" in this driver.
I have found that there are at least three names are used by drivers: "PC Speaker" "Speaker" "Mono" for the same input/output pair (At least on the ISA cards there is only single purpose mono channel - to route the PC speaker).
Which name should be used? I will convert all ISA drivers to the selected name (and fix the OSS mixer to map this name to the "Speaker" control).
I proposed and changed all "Speaker" and "PC Speaker" names to "Beep" in recent ALSA code. The OSS emulation layer is updated as well.
