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.

NAME

       roar_simple_play,  roar_simple_monitor,	roar_simple_record,  roar_simple_filter  - Simple playback, monetoring, recording or filtering via
       RoarAudio

SYNOPSIS

       #include <roaraudio.h>

       int roar_simple_play(int rate, int channels, int bits, int codec, char * server, char * name);

       int roar_simple_monitor(int rate, int channels, int bits, int codec, char * server, char * name);

       int roar_simple_record(int rate, int channels, int bits, int codec, char * server, char * name);

       int roar_simple_filter(int rate, int channels, int bits, int codec, char * server, char * name);

DESCRIPTION

       Open a connection to the roard(1) and creates a new stream for playback, monetoring, recording or filtering.  After you are done  you  need
       to close the connection via roar_simple_close(3).  In case you just don't do anything with the stream the server will kick your connection,
       or, in case of playback warns the user about underruns.

       All those functions are marked obsolete and will be removed soon.  Please upgrade to VS API. See roar_vs_new_simple(3).

PARAMETERS

       rate   The sample rate of the stream.

       channels
	      The nummber of channels in the stream.

       bits   The number of bits per sample of the stream.  Commen values are 8 and 16.

       codec  The Codec of the data you stream to the server.  This has nothing to do with codec of the file you are  playing  back  or  encoding.
	      Default (ROAR_CODEC_DEFAULT) is ROAR_CODEC_PCM_S_BE for signed PCM in big endian.

       server The name of the server. A value of NULL (common case) is used to try default locations.

       name   The  name of the process opening this stream to be listend in the servers meta data.  Should normaly be the name of the player with-
	      out any path or filename being played.  If NULL an internal default is used.

NOTES ON FILTER STREAMS

       Filtering streams should not expected to work with diffrent audio data than  the  server  works	with.	You  should  get  the  values  via
       roar_server_oinfo(3) before opening the stream.

RETURN VALUE

       On success these calls return a filehandle for the stream.  On error, -1 is returned.

EXAMPLES

       Examples  of  these calls are the tools roarcat(1), roarmon(1), roarrec(1) and roarfilt(1).  Just look at there code. They aren't that com-
       plex.
