Hello, currently I am experimenting with different audio players in putting out different bitrates an sample sizes of music directly to the soundcards I have plugged in. The results where mplayer resamples or the alsa library or both or none are not predictable for me. Is there a way to determine wich samplerate the card supports with its driver and which not? I enabled verbose procfs contents already and /proc/asound/cardX/codec#0 seems to deliver this for my onboard intel-hda but my other cards do not have such files. How do I determine hardware supported and accepted but resampled bit rates from the driver's source file? Kind Regards, Konsti |

Use test functions for hw_params for every interested rate. Jaroslav ----- Jaroslav Kysela <pe...@pe...> Linux Kernel Sound Maintainer ALSA Project, Red Hat, Inc. |

The programmer's Point of you :-) Thanks for pointing this out, I found an alsa .c file doing something similair I will extend :-) Kind Regards, Konsti |
