hi,
after much tinkering i am still unable to get out sound out of my MM205
TV card - picture and tuning are both perfect however. using kernel
2.4.0, bttv-0.7.53 (separately) and SBLive (Creative OSS compatible
driver used). since this TV card does not have line out and is based on
BT878KHF, i assume the only way to get sound is via the btaudio module?
both kernel and bttv compile okay and i install the bttv modules over
the kernel ones. although this is a Mandrake 7.2 based machine, i
downloaded a new copy of 2.4.0 kernel source because i wasn't happy with
the patched version that comes with the distribution. i'm going to try
to be as verbose as possible as i'm not sure what is and isn't relevant.
any help would be most appreciated.
thanks,
'tish.

at this point i can happily run xawtv:

ok

now to try audio. i kill off my esd and remove mixer applet, so that my
SBLive module is unused:

now kick up xawtv and using sox for sound (as suggested in
README.btaudio):
[root@necromancer video]# xawtv&

This is xawtv-3.21, running on Linux/i686 (2.4.0)

nothing and lsmod shows that the btaudio module isn't being used.
removeing btaudio and try specifying dsp2:
[root@necromancer video]# rmmod btaudio; insmod btaudio.o debug=1 dsp=2
Jan 24 12:37:37 necromancer kernel: btaudio: driver version 0.4 loaded
[digital audio mode]
Jan 24 12:37:37 necromancer kernel: PCI: Found IRQ 5 for device 00:0a.1
Jan 24 12:37:37 necromancer kernel: PCI: The same IRQ used for device
00:0a.0
Jan 24 12:37:37 necromancer kernel: btaudio: Bt878 (rev 2) at 00:0a.1,
irq: 5, latency: 32, memory: 0xe2800000
now for sox again, lsmod still shows no usage. i had created the dsp2
using:
mknod /dev/dsp2 c 14 3
i suspect that is the cause of problems as i came about to these numbers
after looking through kernel headers in various places.
