Some boards have an extra processor for sound to do stereo decoding and other nice features. The default is the maximum supported speed by kernel bitbang algorithm. These cards are sold by many OEMs too. The only way to capture any kernel messages is to hook up a serial console and let some terminal application log the messages. This makes debugging very difficult for me. Well, you might want to check the video4linux mailing list archive first The decision lock may be removed at the end of the transaction:

Start writing a new one. The default is the maximum supported speed by kernel bitbang algorithm.
To handle the grabber boards correctly, there is a array tvcards in bttv-cards. Very nice card if you only have satellite TV but several tuners connected to the card via composite.
7. The bttv driver — The Linux Kernel documentation
ALSA for example has everything muted by default. This driver used to be part of bttv. You might try to disable this if you have bad input signal quality which leading to unwanted sound dropouts. Thus, both the arbiter and the initiator contain FX compatibility mode logic. They have also stuck an infra-red remote control decoded on the board, I will add support for this when I get time it simple generates an interrupt for each key press, with the key code is placed in the GPIO port.
This page has been accessed 36, times. FM bhtv or AM. Neither function can preempt the other once on the bus. It works just fine in theory and many configurations. Starting with release 0.
The driver for the tea fader chip. A small percentage of core logic devices may start a bus transaction during the same cycle that GNT is de-asserted. Author of this section: Author of this section: The bttv vl4 should print a line like this one use the ‘dmesg’ command to see the kernel messages:.
Check if v4l-conf is installed suid root, it needs root priviliges to do this. The audiomux array holds the btyv values for the different inputs i. Thus the arbiter defaults to the video function at power-up and parks there during no requests for bus access.
Some boards use the i2c bus instead of the gpio pins to connect the mux chip. The driver for the tea fader chip. The Virtual Video Test Driver vivid ALSA for example has everything muted by default. If you have a stereo card, you probably want to insmod this one. This is non PCI 2.
Very nice card if you only have satellite TV but several tuners connected to the card via composite. Bt and others but always in 2 crystal operation??? The only way to capture any kernel messages is to hook up a serial console and let some terminal application log the messages.
v4l: bttv driver update
Hauppauge for telling how the sound input is selected and what components they do and will use on their radio cards. The tuner frequency setting should work but it is possible that the audio multiplexer is wrong. What v4o have to do is figure out the correct values for gpiomask and the audiomux array.
