Problem Details: This fixes the problem of getting extra bytes inserted at the beginning of a recording when using the Apple i2s interface and DBDMA controller. It turns out that we can't just abort the DMA; we have to let it stop at the end of a command, and then wait for the S7 bit to be set before turning off the D...

Problem Details: For some time now, some users of STAC9758 (emu10k1) would have no sound on their front channels. This can be fixed (at least for me) by unmuting head phone volume and setting it to 0dB before removing the 'Front Playback' control.
