hello,

i need help with the sound issue with my installation; i get video and can change channels but no sound; the card is saa1734/saa7131 and it gets detected by knoppmyth.

i have tried mythdora, ubuntu edgy installs also this is the only version that i have any luck getting video out, (by far the best and simplest distro)

please help i am so close to getting it to work.

http://www.mythtv.org/wiki/index.php/KW ... Terminator
this is link to mythtv wiki on the card

http://www.linuxtv.org/v4lwiki/index.ph ... Terminator
this is v4l wiki link (i think studio TV is same as global TV)

i finally got it working, thanks to this wiki, install help...

http://www.mythtv.org/wiki/index.php/KW ... _KnoppMyth


brief how to for knoppies

R5E50 version;

i entered my ip via ssh just after it reached the setup menu
logged in as root

adding options saa7134 card=65 tuner=54 to saa7134 was not needed for me i was getting video but no sound. on normal install

modprobe saa7134-oss helped alot, it created /dev/dsp1 in addition to /dev/dsp so i picked /dev/dsp1 instead of /dev/dsp

i placed the following lines in /etc/init.d/rc.local (after the line ". /lib/lsb/init-functions"):

modprobe saa7134-oss
v4l2-ctl --set-ctrl=mute=0
v4l2-ctl --set-ctrl=volume=10
v4l2-ctl --set-ctrl=automute=0

make sure you add the path correctly for v4l2-ctl location because after entering these commands i was getting "command not found" error on boot and was unable to get sound.

find out the location by entering

#which v4l2-ctl

this should give you path of v4l2-ctl, enter the path on the line PATH=*******

save and close rc.local

enter this
# update-rc.d rc.local defaults

this should do it.

i didnt enter the remote control configuration yet.

will try that soon.


:D

Fresh install of R5F27 on a Dell optiplex gx260

The capture card is a Kworld Global TV Terninator (guess it's the same or similar to the ones mentioned previously). The card was not detected automatically (unlike the previous poster's card), so I added the following to a file called saa7134 in /etc/modprobe.d/

options saa7134 card=65 tuner=54

Got the directions from here http://www.mythtv.org/wiki/index.php/KW ... Terminator
& I see the previous poster did similar.

Also placed lines in /etc/init.d/rc.local as previous poster did,

Getting video OK, but no sound.

Doing a "ls /dev/dsp*" only shows /dev/dsp, this is the built in soundcard.

dmesg shows:

I found a detailed page on saa7134 http://www.linuxtv.org/v4lwiki/index.php/Saa7134-alsa

I tried saa7134-alsa, but this hung the system on reboot.

I've successfully set up Knoppmyth with saa713X cards previously, but this capture card does not have an audio out on the back panel, so I assume the driver needs to grab the audio directly from the card.

Alsa is supposed to be able to do this, guess I would prefer to get saa7134-alsa working over saa7134-oss, but any audio is better than none.

Anyone gotten this card working with R5F27?

Did some more work on this.

If I attempt to use alsa for sounds, as in put the following in /etc/modprobe.d/saa7134:-

install saa7134 /sbin/modprobe --ignore-install saa7134; /sbin/modprobe saa7134-alsa
options saa7134-alsa index=1

When I try to watch TV, just get a blank screen (no video) & it drops back to the main menu after about 1 minute.

However, dsp1 is created.

If I put the following in /etc/modprobe.d/saa7134:-

install saa7134 /sbin/modprobe --ignore-install saa7134; /sbin/modprobe saa7134-oss
options saa7134-oss dsp_nr=1 mixer_nr=1

Then I can see video, but dsp1 is not created.

As I get best results with saa7134-oss & the previous poster got it working with R5E50, I think I'll try that instead of R5F27.

Well it works OK with R5E50, just as nastywindbreaker said. :P

Wonder what broke between R5E50 & R5F27 to cause the saa7134 sound driver to fail with this card.

R5E50 detected the Kworld card automatically, all I had to do was configure the sound as per this link (saa7134-oss) http://www.mythtv.org/wiki/index.php/KW ... _KnoppMyth & now I got sound.

Would have preferred to run the latest Knoppmyth , but it looks like it would be a significant undertaking to get sound working with this card. :?
