 Posted: Sun Mar 26, 2006 7:44 pm Post subject: kernel 2.6.16 and tv-tuner |
 |
|
hello,
i just upgraded to kernel 2.6.16 and now i'm having a problem with my tv-tuner. I can't hear sound from it, just an annoying noice (using in-kernel alsa drivers). It was/is working just fine with kernel 2.6.14... did anyone notice the same problem? I have a pinnacle pctv with the bt878 chip..
thanx in advance

Something is happening. I went from 2.6.15 to 2.6.16 and didn't even boot.
Switched back to 2.6.15 and now tv doesn't work. Had sound for a split second, now nothing. Investigating.
Edit: Fixed my issue. I have no idea why, but somehow in the process of trying the new kernel, the NTSC frequency got changed from nominal to HRC in the tvtime config file. Very strange.

Hi, I had the same problem starting with kernel 2.6.15. I am using Pinnacle PCTV Sat. After searching through the kernel source I found that the /drivers/media/video/bttv-cards.c changed. So I changed the source to this and now it is working prefect again (current kernel gentoo-sources-2.6.16)
| Code: |
[BTTV_BOARD_PINNACLESAT] = {
.name = "Pinnacle PCTV Sat",
.video_inputs = 2,
.audio_inputs = 0,
.svhs = 1,
.tuner = -1,
.tuner_type = -1,
.tuner_addr = ADDR_UNSET,
.no_msp34xx = 1,
.no_tda9875 = 1,
.no_tda7432 = 1,
.gpiomask = 0x01,
.audiomux = { 0, 0, 0, 0, 1 },
.muxsel = { 3, 0, 1, 2},
.needs_tvaudio = 0,
.pll = PLL_28,
.no_gpioirq = 1,
.has_dvb = 1,
},
|
Sorry, don't have the original 2.6.16 kernel source anymore, don't want to emerge now:-) Simply search in the file for Pinnacle PCTV Sat and change the structure. Hope this might help you too...

well.. my tv-tuner is not a sat one.  I checked the sources though and everything looked just fine.. unfortunally... anyway, looking at the latest git-sources i noticed a few patches about fixes/improvements on the audio part of the bttv drivers.. i'll give them a shot asap and report back if anyone is interested..

i upgraded to vanilla 2.6.17rc1 and sound didn't still work. The kernel detects the tuner card just fine. Now if i just remove the bttv module and then reload it, then it works... weird.. kernel 2.6.14 is just fine...

I have the same.
When I checked dmesg then I saw:
| Quote: | bttv: driver version 0.9.16 loaded
bttv: using 8 buffers with 2080k (520 pages) each for capture
bttv: Bt8xx card found (0).
ACPI: PCI Interrupt Link [LNKC] enabled at IRQ 10
ACPI: PCI Interrupt 0000:00:0a.0[A] -> Link [LNKC] -> GSI 10 (level, low) -> IRQ 10
bttv0: Bt848 (rev 1 at 0000:00:0a.0, irq: 10, latency: 32, mmio: 0xcd8ff000
bttv0: using: *** UNKNOWN/GENERIC *** [card=0,autodetected]
bttv0: gpio: en=00000000, out=00000000 in=00ffebff [init]
tveeprom 0-0050: Huh, no eeprom present (err=-121)?
bttv0: using tuner=-1
bttv0: i2c: checking for MSP34xx @ 0x80... not found
bttv0: i2c: checking for TDA9875 @ 0xb0... not found
bttv0: i2c: checking for TDA7432 @ 0x8a... not found
bttv0: i2c: checking for TDA9887 @ 0x86... not found
bttv0: registered device video0
bttv0: registered device vbi0
|
So I think that the module is not loading with proper parameters from modules.autoload
When I try to load module manually:
| Quote: | | modprobe bttv radio=0 card=15 tuner=7 gbuffers=32 |
then in dmesg I see:
| Quote: |
bttv0: unloading
bttv: driver version 0.9.16 loaded
bttv: using 32 buffers with 2080k (520 pages) each for capture
bttv: Bt8xx card found (0).
ACPI: PCI Interrupt 0000:00:0a.0[A] -> Link [LNKC] -> GSI 10 (level, low) -> IRQ 10
bttv0: Bt848 (rev 1 at 0000:00:0a.0, irq: 10, latency: 32, mmio: 0xcd8ff000
bttv0: using: Zoltrix TV-Max [card=15,insmod option]
bttv0: gpio: en=00000000, out=00000000 in=00ffebff [init]
bttv0: using tuner=7
bttv0: i2c: checking for MSP34xx @ 0x80... not found

bttv0: i2c: checking for TDA9887 @ 0x86... not found
tuner 0-0060: All bytes are equal. It is not a TEA5767
tuner 0-0060: chip found @ 0xc0 (bt848 #0 [sw])
tuner 0-0060: type set to 7 (Temic PAL_I (4062 FY5))

bttv0: registered device video0

And now tv works.
Maybe it's problem of modules/autoload with 2.6.16 ? |

My bt878 (ati tv-wonder) card kept me using 2.6.14 until very recently. I was getting all kinds of noise and,
most annoyingly, the tv audio would start playing on boot. I now have a stable setup with no audio noise:
kernel 2.6.16-gentoo-r3
alsa-* 1.0.11
I do not load bttv in /etc/modules.autoload.d/kernel-2.6. instead I let that module load automatically when needed.
To feed the bttv module the correct parameters, I do this:
create a /etc/modules.d/bttv file, containing the options you want to feed modprobe (insmod). in my case i use:
| Code: | alias char-major-81 bttv
pre-install bttv /sbin/modprobe tuner; /sbin/modprobe msp3400
options bttv card=63 tuner=2 |
Run 'modules-update' to generate a new /etc/modules.conf. After you do this, 'modprobe bttv' (or 'bttv' in kernel-2.6)
should use your options. |
