When I execute sudo modprobe snd_bt87x, I can't capture audio from my
tv capture card (mencoder segfaults). It only works when I execute
sudo modprobe snd_bt87x load_all=1. Then it seems to work ok.
When I issue sudo modprobe snd_bt87x load_all=1, the following lines
appear in dmesg:
unknown card 0x878-0x1554:0x4011, using default rate 32000
please mail id, board name, and, if it works, the correct digital_rate
option to <alsa-devel@xxxxxxxxxxxxxxxx>
I am obeying the request and mailing this information to you. I have no
idea what is the correct digital_rate option; all I know is that the
default seems to work ok. I have a cable connecting the sound output of
the tv card to the line in of my sound card; it seems that when wathing
tv through mplayer this is the mechanism used (and it works ok).
However, when recording tv through mencoder, it seems to use snd_bt87x
(in fact, it does not work if snd_bt87x is not loaded), and it also
works ok.
The card option I pass when loading the module bttv is card=139.
According to /usr/src/linux/Documentation/video4linux/CARDLIST.bttv,
this corresponds to the card
Prolink PixelView PlayTV MPEG2 PV-M4900
In fact, there is a sticker in the PCB that reads (if my
eyes are not failing me) PixelView PV-M4900 FM.RC
The full output of dmesg is attached to this email.
If you need any additional information please contact me directly,
since I will now unsubscribe to this list.
Some possibly useful information:
