These two ioctls are not part of the current version of OSS and were considered obsolete. However, their behaviour is not the same as their old one, so this implementation is specific to FreeBSD. Older OSS versions had the MUTE ioctls take and return an integer with a value of 0 or 1, which meant that the _whole_ mixer is unmuted or muted respectively. In my implementation, the ioctl takes and returns a bitmask that tells us which devices are muted. This allows us to mute and unmute only the devices we want, instead of the whole mixer. The bitmask works the same way as in DEVMASK, RECMASK and RECSRC. Integrated the hardware volume feature with the new mute system.
