em28xx: no sound on board 1b80:e309 (sveon stv40)

Hello again!

I managed to obtain a nice video input from my sveon usb stick using
last em28xx v4l drivers from git and giving the module the hint
card=19.

But I have no audio.The card works flawlessy in windows.

The internal chipsets in the card are:
- USB interface: em2860
- Audio ADC: emp202
- Video ADC: saa7118h (philips)

Attached is the relevant dmseg output.

The usb audio card card correctly shows in pulseaudio volume control
and is recognized as hw.2 by alsa:
$ arecord -l
**** List of CAPTURE Hardware Devices ****

card 2: STV40 [USB 2861 Device (SVEON STV40)], device 0: USB Audio [USB Audio]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

However, I'm not able to record any sound from it and mplayer says "no audio":

Maybe has something to do with the last line in dmesg:

Any ideas?

Re: em28xx: no sound on board 1b80:e309 (sveon stv40)

[Mario Ceresa]

Ok boys: just to let you know that everything works now.

thinking that the problem was with the audio input, I noticed that
card=64 had an amux while card=19 no.

.amux     = EM28XX_AMUX_LINE_IN,

So I tried this card and modified the mplayer options accordingly:

mplayer -tv device=/dev/video0:input=0:norm=PAL:forceaudio:alsa:immediatemode=0:audiorate=48000:amode=1:adevice=hw.2
tv://

notice the forceaudio parameter that reads the audio even if no source
is reported from v4l (The same approach with card=19 does not work)

The output was a bit slugglish so I switched off pulse audio control
of the board (https://bbs.archlinux.org/viewtopic.php?id=114228) and
now everything is ok!

I hope this will help some lonenly googlers in the future :)

Regards,

Mario

Hi Mario,

Since you've spent the time to figure out the details of your
particular hardware, you should really consider submitting a patch to
the em28xx driver which adds your device's USB ID.  That would allow
others who have that hardware to have it work "out of the box" with no
need for figuring out the correct "cardid" value through
experimentation as you had to.

Cheers,

Devin

Hi Mario,

Plese send it with your Signed-off-by:

It is a requirement for merging the patches upstream.

Hi Mauro,
Here it is. Does the "Signed-off-by:" go in the changelog, right?

Many thanks to all the developers for the hard work: it is a joy to
see the card working :)

Best,

Mario
