Hello, A number of users have intermittently(?) been hitting a crash in alsa-lib 1.0.27 [1, 2] related to the softvol plugin. I'm not able to reproduce this reliably, so can't find an easy way to debug/fix.
However, this raises a tangential question - why do we need softvol to be plugged for 'front' at all? David explained to me that this is to guarantee the existence of a PCM control. Perhaps I don't fully understand this, because I'm unconvinced by the reason. Could someone explain/refute?
This is especially bad for us, from PulseAudio's perspective, because we aren't getting a zero-copy path.
Cheers, Arun
