You can try GPIO pin up/down for each pin. Also each pin has two directions, so you'll have 8 x 2 x 2 trials. For example, to test GPIO 3, pass 0x08 (= 1 << 3), try the commands below and check aplay at each. (the lines '//' are just my comments) // dir = 0, data = 1 hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_MASK 0x08 hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DIR 0x00 hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DATA 0x08 // dir = 0, data = 0 hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_MASK 0x08 hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DIR 0x00 hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DATA 0x00 // dir = 1, data = 0 hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_MASK 0x08 hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DIR 0x08 hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DATA 0x00 // dir = 1, data = 1 hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_MASK 0x08 hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DIR 0x08 hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DATA 0x08 Repeat these for each GPIO pin, from 0 to 7. One another possibility is to use the output pin NID 0x0f. For testing this, build with the reconfig feature (usually enabled), then change the pin 0x0f default config, such as echo 0x0f 0x90171111 > /sys/class/sound/hwC0D0/user_pin_configs then quit all sound apps and reconfigure echo 1 > /sys/class/sound/hwC0D0/reconfig Restore the mixer setup once via alsactl alsactl restore Then check the mixer volumes again, try aplay. With this setup, try GPIO procedures above, too. thanks, Takashi _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
