And there is a problem in CS46xx.conf file, i need to remove the hook on the rear pcm to permit multiple surround40 subdevices to be opened. ====================================================================== ---------------------------------------------------------------------- Raymond - 08-01-06 06:45 ---------------------------------------------------------------------- In theory, you should able to run 31 instances of 'speaker-test -c 2 -t wav' concurrently , the 32th instances will be blocked on cs46xx If you specify different rate in 'speaker-test -Dhw:0,0 -c 2 -r 8000 -t sine', the driver only allow to play DSP_MAX_SRC_NR instances different rates. if (ins->nsrc_scb >= DSP_MAX_SRC_NR) { snd_printk(KERN_ERR "dsp_spos: to many SRC instances\n!"); >> For testing I tried to play back more than 32 channels via speaker-test . I did >>this for checking whether channels 33 and above would go on the second AC97. But ... >> 1) The channels above 32 just produce nonsense sounds (short, looping sounds) >> 2) The volume of the nonsense soundss could not be controlled (not by KMix, and >> also not by alsamixer) No, running speaker-test -c N with N > 2 on default device 'plughw' of cs46xx is the side effect of 'plug' plugin in CS46xx.conf Try open different device "default", "hw:0", "plughw:0" , "surround40" and "surround51" snd_pcm_t *pcm; snd_pcm_hw_params_t *hwparams; int channel_max; if ( snd_pcm_open(&pcm, "default", SND_PCM_STREAM_PLAYBACK, 0) < 0 ) printf("Cannot open pcm.\n"); else { snd_pcm_hw_params_alloca(&hwparams); snd_pcm_hw_params_any(pcm, hwparams); snd_pcm_hw_params_get_channels_max(hwparams, &channel_max); printf("max channels = %d\n",channel_max); snd_pcm_close(pcm); }; ---------------------------------------------------------------------- Raymond - 08-03-06 04:26 ---------------------------------------------------------------------- >> The only thing I can say is this: I got all those duplicated devices (like >> PCM.0, PCM.1 and Master.0, Master.1).
