.SH "DESCRIPTION"
.PP
Changes the rate of the given input/output on the codec.
If the codec doesn't support VAR, the rate must be 48000 (except
for SPDIF).
.PP
The valid registers are AC97_PMC_MIC_ADC_RATE,
AC97_PCM_FRONT_DAC_RATE, AC97_PCM_LR_ADC_RATE.
AC97_PCM_SURR_DAC_RATE and AC97_PCM_LFE_DAC_RATE are accepted
if the codec supports them.
AC97_SPDIF is accepted as a pseudo register to modify the SPDIF
status bits.
.PP
Returns zero if successful, or a negative error code on failure.
