SND_AC97_SET_RATE(9)                    Control/Mixer API                    SND_AC97_SET_RATE(9)



NAME
       snd_ac97_set_rate - change the rate of the given input/output.

SYNOPSIS
       int snd_ac97_set_rate(struct snd_ac97 * ac97, int reg, unsigned int rate);

ARGUMENTS
       ac97
           the ac97 instance

       reg
           the register to change

       rate
           the sample rate to set

DESCRIPTION
       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).

       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.

RETURN
       Zero if successful, or a negative error code on failure.
