snd_ac97_set_rate — change the rate of the given input/output.
int snd_ac97_set_rate ( | struct snd_ac97 * ac97, |
| int reg, | |
unsigned int rate); |
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.
Returns zero if successful, or a negative error code on failure.
