Changes: -remove dma reset in stop_{dac,adc} (from ICH4 manual: contents of all Bus master related registers to be reset; so, probably some registers are not re-initilized properly on consecutive re-opening of /dev/dsp ???) -remove writes to OFF_CIV, instead set LVI relative to CIV
and some stuff that was already in the last diff I send to the list: -implement a codec ID <-> IO register offset mapping -in i810_ioctl, case SNDCTL_DSP_CHANNELS: only touch bits 20:21 off GLOB_CNT (multichannel capabilities) -AMD 8111 has 6 hw channels so I must have mmio (but I don't have any docs to verify this) -minor fixes
