No sound from Terratec Grabster AV 350

So I have an Terratec Grabster AV 350 connected to a VHS player with a scart-cable.
The picture is perfect (as perfect as VHS gets), but I can't get any sound.

ALSA recognized the device as a sound card, and I could configure it with KDE's pulseaudio tools.
I checked several times that it's not muted.

None of these commands gave out any errors, they just resulted in complete silence.

ffplay -f pulse -i "alsa_input.usb-0ccd_Grabster_AV_350-01.analog-stereo" 
ffplay -f alsa -i hw:2
arecord -D hw:2 test.mp3

I tried changing the default pulseaudio source to Grabster and then ran:

ffplay -f pulse -i default

Which didn't work, no surprises there.

Then I tried uninstalling pulseaudio, running the same commands. Again nothing but silence.

I googled a bit and found something related to the module "em28xx" (a thread on Ubuntus forums, from 5-6 years ago).
So I tried doing what they suggested in that thread:

sudo modprobe -r em28xx_v4l em28xx
sudo modprobe em28xx card=68
sudo modprobe em28xx_v4l

That didn't help at all, and neither did changing card=68 to card=67.

I tried running Windows 8.1 in VirtualBox, and sort of got audio (very choppy), but this time the video was missing completely.

Any ideas?

Edit:
The card numbers are from here: https://github.com/torvalds/linux/blob/ … 8xx.h#L118
