[linrad] problem setting up "non-standard" AD hardware
Hi all,
I have a problem setting up my AD hardware with Linrad.
My system is a Mandrake 9.1 with two "audio" boards.
Both audio boards have been tested and work with programs like SOX, and the system audio mixer.
All the installation process was perfect: svgalib, nasm, Linrad 01-17. Everything OK.
My first audio board is a Sound Blaster compatible card. In the U option, Linrad detects it under /dev/sound/dsp and can be configured without any problem.
The second audio board is a Bt878a TV card. It can be used as ADC up to 448000 samples per second and 16 bits. I know this can be a bit strange but you can read the setup process here: http://www.domenech.org/bt878a-adc/index-e.htm
In the U option Linrad says:
=cut=====================================
Checking device drivers
00:/dev/sound/dsp 44100 Hz 2 Chan. 16 bit
02:/dev/sound/dsp1 32000 Hz 2 Chan 16 bit
03:/dev/sound/dsp2 448000 Hz 2 Chan 16 bit
Select device for input by line number _
=cut=====================================
If I select "00" it works but if I select "03" (the Bt878 ADC) it says "ERROR (press any key)". Doesn't matter if I try "03","3", "02", "2", always the same message.
I know this is not a standard sound device and maybe has not much sense to worry about, but I think it's a pity to get so close (Linux and Linrad detects the hardware) and loose the opportunity to play with higher frequencies with low cost hardware.
At the bottom you have my "soundboard_init.log".
thanks!
