Yuir and Multimedia's
I have put together a new bt848 driver where you can prevent the reset
of the
MSP3400 stereo audio chip.
The driver currently supports 3410/3415 audio chips but not the original
3400C chip.
You can get audio on the old 3400C chips by
a) booting Windows, running the Hauppauge Windows software
b) doing a soft reboot into FreeBSD. The MSP3400C chip retains it
settings.
The -current and -stable driver resets all MSP34xx chips, erasing any
Windows settings.
The new driver can block the MSP34xx reset by adding the following to
your
kernel config
options BKTR_NO_MSP_RESET
A new driver is available from the Bt848 pages at the Telepresence Group
web site
http://telepresence.dmem.strath.ac.uk/bt848
If you want to try it, do the following
1) edit your kernel config.
change this line
device bktr0
to this
device bktr0
options BKTR_NO_MSP_RESET
You will need to run 'config xxxx' too.
2) goto http://telepresence.dmem.strath.ac.uk/bt848
Look for the Beta Test drivers section and follow the link for
the beta driver for freebsd 3.1 or 3.x-stable or 4.x-current
3) download the .c and .h files and replace the corresponding files in
your
kernel source tree. (/sys/pci and /sys/i386/include)
4) rebuild your kernel and of you go.
Good luck..
bye
Roger
