Perhaps, this could be 'depends on SOUND'. (in that case, arch/um/configs/*_defconfig needs modification). Just my two cents. Reviewed-by: Masahiro Yamada <masahiroy@kernel.org>

Use "select"s to ensure that the required kconfig symbols are set as expected. Drop HOSTAUDIO since it is now equivalent to UML_SOUND. Allow SOUND with UML regardless of HAS_IOMEM. Otherwise there is a kconfig warning for unmet dependencies. (This was not an issue when SOUND was defined in arch/um/drivers/Kconfig. I have done 50 randconfig builds and didn't find any issues.)
