.SH "DESCRIPTION"
.PP
Changes the rate of the given input/output on the codec\&. If the codec doesn\*(Aqt 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\&.
.SH "RETURN"
.PP
Zero if successful, or a negative error code on failure\&.
