 Posted: Tue Mar 22, 2005 9:10 am Post subject: [solved] dmesg cluttered with one line |
 |
|
My dmesg file is useless because the driver of my tv card keeps adding lines to it. Does this mean there is something wrong with the settings?
The TV card is a Multimedia video controller: Conexant Winfast TV2000 XP (rev 05), according to lspci. I use a 2.6.10-gentoo-r6 kernel.
These are the loaded modules:

This is a part of dmesg, there is no other information in it.
| Code: | cx88[0]/0: AUD_STATUS: 0x1bf2 [mono/no pilot] ctl=BTSC_AUTO_STEREO
cx88[0]/0: AUD_STATUS: 0x1bb2 [mono/no pilot] ctl=BTSC_AUTO_STEREO
cx88[0]/0: AUD_STATUS: 0x1c32 [mono/no pilot] ctl=BTSC_AUTO_STEREO

If I need to include more information, please ask

I somehow have the feeling bumping posts is inappropriate.
The question I have is purely a kernel question. At what forums can I ask questions like this? Is there perhaps a site with documentation about the driver?
Thanks in advance. |

I finally found some info about this:

These are debug messages which can be disabled with the audio_debug
module parameter:
/sbin/modprobe cx8800 audio_debug=0 |
When I do that I get the message:
| Code: | | cx8800: Unknown parameter `audio_debug' |
and | Code: | | cx8800: Unknown parameter `debug' |
when I try "debug=0".
And then I even found someone reporting it to work:
https://forums.gentoo.org/viewtopic.php?t=130889
| Quote: | | I finally got sound output using the latest video4linux drivers by passing the debug=1 option to the cx8800 module. Thanks to Gerd Knorr for that. I'm not sure your prob is related to this or your alsa config. Physically, I have a small audio cable that runs from the backplane of the card into the line-in socket so there's very little chance of confusion there. |
I have tried | Code: | /sbin/modprobe cx8800 audio_debug = 0
/sbin/modprobe cx8800 audio_debug=0
/sbin/modprobe cx8800 'audio_debug=0'
/sbin/modprobe cx8800 "audio_debug=0"
/sbin/modprobe cx8800 debug=0 |
but no results but the 'unknown parameter" error.
Where can I find info about what parameters are known? The docs that come with the kernel tell me nothing about the parameters, and neither does the author's site. |
