You have /dev/dsp and /dev/dsp[1-7], right?

Hi, I am working on an ALSA audio driver for my device which is very similar to BT878. It will have at least 8 audio devices in a single card. Now, the audio driver is working correctly. I can use aplay to play the audio file which is created by arecord. To identify audio devices, I am using hw:1 ~ hw:8 dvice description for my audio devices, because hw:0 is the sound card. In order to make the old application work, I know that ALSA emulates all my devices to have OSS nodes respectively. I guess that It should have /dev/dsp to /dev/dsp8, and /dev/dsp is for sound card, and /dev/dsp1 to /dev/dsp8 are for my audio devices. However, I can not find /dev/dsp8 in my system. I guess ALSA can only emulate 8 audio device totally. That the reason I can not see the 8th audio device. Am I right? How can I create the /dev/dsp8 manually? By the way, if someting is wrong above, please correct me. Thank you. _______________________________________________ Alsa-devel mailing list Alsa-devel@alsa-project.org http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
