Message-ID: <d2e0758638f54ddb9fce57fc85f61d27@in.bosch.com> (raw)
Hi All,
I have two virtual device pointing to same Alsa card ,with different bindings
When audio played on both device [dmix_4_channels and dmix_2_channels] in parallel. Audio played on dmix_2_channels is getting corrupted.
Validated with alsa versio : 1.2.3
Please let me know how to make it work with below configuration.
Alsa configuration used for testing:
*************************************************
pcm.dmix_4_channels {
type dmix
ipc_key 5678293
ipc_perm 0660
ipc_gid audio
bindings [0 1 2 3]
slave {
pcm "hardware"
channels 4
periods 4
period_time 40000
}
}
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.hardware {
type hw

}
