When using alsa-lib and the at91 soc driver (pcm+i2s) I can playback PCM samples using both aplay and test/pcm. Using softvol I can also reduce the volume of the playback. The problem I have is that the playback volume (with softvol=100%) is not very loud. The volume is the same even without the softvol plugin. The PCM codec has no hw volume control. According to our hw team the sound level should be much higher. Is there a default PCM attenuation (volume reduction) built into alsa lib? If so, how can it be adjusted? Thanks, Michel
