The Advanced Linux Sound Architecture (ALSA) - library

When dmix uses non-interleaved mixing mode the offset and step width
to sum_buffer was calculated by using the dmix channels instead of
the slave channels. This leads to audio distortions due to frame
corruption.
example:
- With below configuratio, Do aplay on both device in parallel for
audio distortion
pcm.dmix_2_channels {
type dmix
ipc_key 5678293
ipc_perm 0660
ipc_gid audio
bindings [0 1]
slave {
pcm "hardware"
channels 2
periods 4
period_time 40000
}
}
pcm.dmix_1_channels {
type dmix
ipc_key 5678293
ipc_perm 0660
ipc_gid audio
bindings [0]
slave {
pcm "hardware"
channels 1
periods 4
period_time 40000
}
}
pcm.hardware {
type hw
card 0
channels 2
rate 48000
format S16_LE
}
