Device Kworld 305u sound problem

[ctgmao]

I have a plate of tv kworld 305u, succeeded see the video but the sound is not working, tried some other drivers

I am using http://mcentral.de/hg/ ~ mrec/v4l-dvb-kernel tried kernel but not worked.

Output of dmesg

I have a WinTV-HVR-950 (same driver), and it is a known problem that sound is broken. See http://mcentral.de/wiki/index.php/Em2880#watching_analogue_TV for some help.

I seem to remember a fixaudio.sh or so (I took the actual line being excecuted and put it in its own script) that was really hard to find, but did work with tvtime.


Remeember that this thing has its own fake sound card, and you have to pipe the audio over.


Hope it helps some,

Thanks

Noticed that this is a common problem.

I will examine the link

My audio card is intel but in demsg says it is ac97, perhaps this is the problem.

In the output of dmesg appears a mistake

Hi,

I think my problem is because of snd_usb_audio I looked at that connect to the plate in the USB it should create a new device / dev/dsp1, but he does not recognize. See the output of the command:

[poly_poly-man]

Right after loading snd-usb-audio, give dmesg | tail or so.

Hi,

Discovered a new information, plugar the plate it does not recognize the part of the audio usb,
But after running:

Hi,

Thanks for helping.

The output of dmesg had a message on a stable version of v4l-kernel to the kernel
2.6.19. Testing this kernel and the board worked sound and video.

He noted that this kernel not created the device / dev/vbi0. He just created the / dev / video.
Reading the documentation of v4l-kernel and with the help of dmesg realized that the device was for
Not analogue and digital plates.

Returning to the kernel 2.6.23 did a test, raised the em28xx with a driver that was not analogue and digital
So it does not create the / dev/vbi0. It worked perfectly the audio and video.
