Hey,
I have a Sound Blaster Live! card connected to 7.1 amp via optical
coax cable. When I watch DVDs or anything with xine I get nice, rich
full surround sound. However, when I watch tv shows recorded within mythtv
there is no output from LS or RS. The front , center and rear channels
all output.
I have attempted to duplicate the rear channels using ttable and output
the duplicated sound in the side channels. However, I am unable to
produce any sound using route and dmix. Is this possible?
I have tried tinkered with some of the below configuration. Only
digital-hw on it's own produces sound.
pcm.digital-hw {
type hw
card Live
device 2
}
pcm.upmix {
type route
slave.digital-hw # I have tried setting to this
#to digital-hw and dmix71 and neither produces no sound.
slave.channels 8
ttable.0.0 1
ttable.1.1 1
ttable.2.2 1
ttable.3.3 1
ttable.4.4 1
ttable.5.5 1
ttable.2.6 1
ttable.3.7 1
}
pcm.dmix71 {
type dmix
ipc_key 1024
slave {
pcm digital-hw
rate 48000
channels 6
period_time 0
period_size 1024
buffer_time 0
buffer_size 1024 # Increasing this simply produces
# a studdering du-du-du-du-du sound.
}
}
