 Posted: Tue Jun 29, 2004 3:31 am Post subject: Another saa7134 tv tuner no audio problem |
 |
|
Ok ... I hope someone can help. I read the forums, and the video4linux docs, but I still can't get this working.
I've got a LifeView FlyVideo 3000 FM tv tuner card, and I can't get any sound to play in tvtime. The video works great.
Here's my hardware:
| Code: | # lspci
...
0000:01:07.0 Multimedia controller: Philips Semiconductors SAA7133 Audio+video broadcast decoder (rev 10)
... |
I have everything compiled in as a module, and after I modprobe "saa7134 card=2" this is lsmod output:
| Code: | Module Size Used by
tuner 16076 0
saa7134 85004 0
video_buf 15556 1 saa7134
v4l2_common 4864 1 saa7134
v4l1_compat 11652 1 saa7134
ir_common 3460 1 saa7134
videodev 7168 1 saa7134 |
The thing that I can't figure out is which tuner type to load. The video4linux doc says the module doesnt detect it automatically, so you can pass it with the type.
I'm using gentoo-dev-sources-2.6.7 and here's what my options are:
| Code: | # grep NTSC CARDLIST.tuner
tuner=2 - Philips NTSC (FI1236,FM1236 and compatibles)
tuner=6 - Temic NTSC (4032 FY5)
tuner=8 - Temic NTSC (4036 FY5)
tuner=17 - Philips NTSC_M (MK2)
tuner=21 - Temic NTSC (4039 FR5)
tuner=27 - LG NTSC+FM (TPI8NSR01F)
tuner=31 - SHARP NTSC_JP (2U5JF5540)
tuner=36 - Temic NTSC (4136 FY5)
tuner=39 - LG NTSC (newer TAPC series)
tuner=42 - Philips 1236D ATSC/NTSC daul in
tuner=43 - Philips NTSC MK3 (FM1236MK3 or FM1236/F) |
I've tried:
| Code: | | modprobe saa7134 card=2 tuner=x |
with every one of those tuner options, and each time I start tvtime, the audio doesnt work. Sometimes there is static when I switch channels, but that's it.
Anyone have a clue of how to fix this thing? Of coruse it works in Windows, and I'm at my wit's end.
Sorry if this post is a little thrown together -- I've been playing with this for hours and my mind is mush.

Another poor soul with SAA7133 problems - sorry I know how frustrating this can be. I have an AOPEN VA1000 POWER with the same SA7133 chip. I'm using gentoo-dev-sources-2.6.7-r6.
First of all I noticed you have your card identified as "2" from /usr/src/linux/Documentation/video4linux/CARDLIST.saa7134. That could be part of the problem as mine is listed as "18" but in reality it's really 17 as shown here:
hist:500 cmnd:1 jobs:0 # dmesg | grep saa
saa7130/34: v4l2 driver version 0.2.11 loaded
saa7133[0]: found at 0000:02:0e.0, rev: 16, irq: 3, latency: 32, mmio: 0xec800000
saa7133[0]: subsystem: 1131:0000, board: AOPEN VA1000 POWER [card=17,insmod option]
saa7133[0]: board init: gpio is 10040
saa7133[0]: dsp access wait timeout [bit=WRR]
saa7133[0]: dsp access wait timeout [bit=WRR]
saa7133[0]: Huh, no eeprom present (err=-5)?
tuner: chip found at addr 0xc0 i2c-bus saa7133[0]
tuner: type set to 2 (Philips NTSC (FI1236,FM1236 and compatibles)) by saa7133[0]
saa7133[0]: registered device video0 [v4l2]
saa7133[0]: registered device vbi0
I check out some other cards and it appears they are all off by 1. You might try using card=1 for your LifeView FlyVIDEO3000.
As you see by the above information the saa7133 chipset should set the tuner type to the correct value if you get the card number right.
Now to what audio performance I have running either TVTime or XAWTV:
Only "right channel audio"!
From /usr/src/linux/Documentation/video4linux/README.saa7134, I checked out http://bytesex.org/patches/ and fouund there is a patch for the saa7134 kernel driver:
http://dl.bytesex.org/patches/2.6.7-1/32_bttv-input-2.6.7.diff
I haven't tried applying it, but looking at it in an editor there appears to be some changes to the audio portion of the driver. I haven't tried patching the kernel to see if it fixes my problem. Right channel sound is better then no sound at all.
Hope this helps some. |

Hei sdibb
I have the 7134 card with its audio cable connected to AUX on my motherboard, so I have enabled 'aux' in Kmix and turned the wick up..
have you done something similar?
mvh

I have the same card and use card=2 and tuner=39
Place it in /etc/modules.d/saa7134 like this
| Code: |
options saa7134 card=2 tuner=39
|
Check your kernel version number. It works flawless for me up to gentoo-dev-sources 2.6.5-r1, but all versions after that don't have sound. |
