Hello
Now that I have my pcm playback working with aplay with our at91 aSoc sound driver I would like to control the volume with softvol.
I followed the instructions from http://alsa.opensrc.org/How_to_use_softvol_to_control_the_master_volume and I have the following asound.con file in /etc
pcm.!default { type plug slave.pcm "softvol" }
pcm.softvol { type softvol slave { pcm "plughw:0,0" } control { name "PCM volume" card 0 } }
When I play a wav file directly to the device it works fine:
# aplay -Dplughw:0,0 Front_Center.wav Playing WAVE 'Front_Center.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono
but when I try to use the default softvol device I get the following output (and no sound):
# aplay Front_Center.wav Playing WAVE 'Front_Center.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono ALSA sound/core/control.c:1244: unknown ioctl = 0xc2c45512 ALSA sound/core/control.c:1244: unknown ioctl = 0xc2c45512 ALSA sound/core/control.c:1244: unknown ioctl = 0xc2c45512 ALSA sound/core/control.c:1244: unknown ioctl = 0xc2c45512 ALSA sound/core/control.c:1244: unknown ioctl = 0xc2c45512 ...
Does anyone have any ideas as to why this is happening?
