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.

NAME

       roar_vs_new_simple, roar_vs_new_playback - Create new VS objects

SYNOPSIS

       #include <roaraudio.h>

       roar_vs_t * roar_vs_new_simple(const char * server, const char * name, int rate, int channels, int codec, int bits, int dir, int * error);

       roar_vs_t * roar_vs_new_playback(const char * server, const char * name, int rate, int channels, int codec, int bits, int * error);

DESCRIPTION

       These  functions create a new VS object with a already connected data connection.  The functions connect to the server server with applica-
       tion name name.	They take the audio parameters as arguments rate, channels, codec, bits.

       roar_vs_new_simple() takes the stream direction as parameter dir.

       roar_vs_new_playback() is equivalent to roar_vs_new_simple() expect that it does not take the direction parameter  but  uses  ROAR_DIR_PLAY
       (waveform playback). It may be implemented as a macro.

PARAMETERS

       server The server to connect to. NULL for defaults.

       name   The  application	name.  This  should  be  something the user can use to identify the application.  It MUST NOT be the application's
	      binary name or the value of argv[0].

       rate, channels, codec, bits
	      The audio parameters for the new stream: sampling rate, number of channels per frame, used codec and number of bits per sample.

       dir    This is the stream direction. Common values include ROAR_DIR_PLAY for waveform playback, ROAR_DIR_MONITOR for  waveform  monitoring,
	      ROAR_DIR_RECORD for waveform recording.  For MIDI ROAR_DIR_MIDI_IN and ROAR_DIR_MIDI_OUT is used.

       error  This  is	a pointer to a integer used to store the error value in case of error.	This can be NULL if not used but it is very recom-
	      mended to use this error value to report good error messages to the user.

RETURN VALUE

       On success these calls return a new VS object.  On error, NULL is returned.

EXAMPLES
