Revision as of 22:26, 23 June 2007
I have an AverMedia Cardbus (E500) which works fine with Windows XP. In recent 2.6.11 kernels there is this line in drivers/media/video/saa7134/saa7134.h:
#define SAA7134_BOARD_AVERMEDIA_CARDBUS 46
but the corresponding entry in saa7134-cards.c didn't work for me, I couldn't tune in any channel.
To make is work, I did the following:
1. Got the (almost) latest kernel from www.kernel.org (2.6.12-rc1) with support for tda8290+75.
2. In saa7134-cards.c I replaced the the board config entry for this card with the following:
[SAA7134_BOARD_AVERMEDIA_CARDBUS] = { /* Kees.Blom@cwi.nl */ .name = "AVerMedia Cardbus TV (E500)", .audio_clock = 0x187de7, .tuner_type = TUNER_PHILIPS_TDA8290, .inputs = {{ .name = name_tv, .vmux = 1, .amux = LINE2, .tv = 1, },{ .name = name_comp1, .vmux = 3, .amux = LINE2, },{ .name = name_svideo, .vmux = 8, .amux = LINE2, }}, .radio = { .name = name_radio, .amux = LINE1, }, },
3. Added this code in saa7134-cards.c, under the function saa7134_board_init1():
case SAA7134_BOARD_AVERMEDIA_CARDBUS: /* wake-up tuner chip */ saa_andorl(SAA7134_GPIO_GPMODE0 >> 2, 0x0FFFFFFFF, 0x0FFFFFFFF); saa_andorl(SAA7134_GPIO_GPSTATUS0 >> 2, 0x0FFFFFFFF, 0x0FFFFFFFF); break;
4. With these compiled, installed and rebooted, I issued
modprobe saa7134 oss=1
This resulted in the following lines in /var/log/messages:

5. Video
At this point I could tune-in tv channels and see tv pictures with xawtv, tvtime and kdetv.
6. Audio
To get tv sound, I first typed in a terminal while tvtime was running (after killing artsd):
sox -tossdsp /dev/dsp2 -tossdsp /dev/dsp
However, this command is just a hack and sound terminates when changing channels in tvtime.
A better solution is to use Hartmut Hackman's code in CVS (as of 10 May 2005). I downloaded these files from linuxtv.org:
saa7134-oss.c,v 1.14 2005/05/18 22:45:16 hhackmann saa7134-tvaudio.c,v 1.23 2005/05/18 22:46:17 hhackmann
and set
.amux = TV
After compiling and loading the module saa7134, the commands:
tvtime --mixer=/dev/mixer:vol& sox -c 2 -s -w -r 32000 -t ossdsp /dev/dsp2 -t ossdsp -w -r 32000 /dev/dsp &
starts tvtime with sound and sound is now restored when changing channels.
The only flaw left is that, when changing channel, during ~1 sec. sound of the new channel is heard, followed by ~1 sec. of noise, whereafter sound is restored properly.
6. Problems left
- is the code to wake up the tuner chip correct? Isn't trying to set all bits high a little bit too much?
- so far, I haven't tested the S-Video and Composite inputs of this card.
Edit:Both S-Video and Composite inputs work fine, even before changes to saa7134-cards.c. I needed to pass the module option
modprobe saa7134 card=46 oss=1
because the card type was not auto detected.
This was done on a Dell Inspiron 4150 with Fedora Core 3 Installed.

It looks like that all the source changes are in the 2.6.15 kernel (and probably som lower versions). //jostmart
