Hey,
I am attempting to work out why I can't get my
btaudio driver to peacefully coexist with bt878.o from the dvb-kernel
driverset.
I am using a 2.4.22 kernel built from source on a
MythTV based multimedia box.
I have 3 cards in the server:
Avermedia DVB-T (BT878)
PV878 Analogue TV (BT878 based)
Miro DC10 (Zoran)
The Pixelview is hardware hacked to provide a
composite video output to the DC10 which then encodes to MJPEG
onboard.
I am using the btaudio driver to pull the audio off
the Pixelview card and feed it into MythTV.
When I load the btaudio driver it happily registers
4 additional dsp devices - two for each of the BT878 based cards and everything
works as expected.
However, when I try to bring the DVB card into
play, I am required to load:
dvb-core, bt878,
dvb-bt8xx, sp887x
With btaudio loaded, any attempt to load the bt878
module fails.
btaudio: driver version 0.7 loaded
[digital+analog]
btaudio: Bt878 (rev 17) at 02:09.1, irq: 10, latency: 32, mmio: 0xee000000 btaudio: using card config "default" btau dio: registered device dsp0 [digital] btaudio: registered device dsp1 [analog] btaudio: registered device mixer0 btaudio: Bt878 (rev 17) at 02:0b.1, irq: 5, latency: 32, mmio: 0xec800000 btaudio: using card config "default" btaudio: registered device dsp2 [digital] btaudio: registered device dsp3 [analog] btaudio: registered device mixer1 bt878: AUDIO driver version 0.0.0 loaded Conversely, any attempt to load btaudio after
loading the DVB driverset fails with:
/lib/modules/2.4.22/kernel/drivers/sound/btaudio.o: init_module: No such
device
The bt878 module appears to claim audio
functionality when loaded successfully, however I cannot detect any new audio
devices being available through this module.
The upshot is, that I can either use my analogue
setup, or my DVB setup, but not both together.
Now, there is every possibility I am missing
something obvious, but any suggestions would be helpful...
cheers
Mark
