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 On 6 January 2012 18:48, Mario Ceresa <mrceresa@xxxxxxxxx> wrote: > 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 0: Intel [HDA Intel], device 0: AD198x Analog [AD198x Analog] > Subdevices: 3/3 > Subdevice #0: subdevice #0 > Subdevice #1: subdevice #1 > Subdevice #2: subdevice #2 > 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": > $ mplayer -tv device=/dev/video0:input=1:norm=PAL:alsa:immediatemode=0:audiorate=48000:amode=1:adevice=hw.2 > tv:// > MPlayer SVN-r33996-4.6.1 (C) 2000-2011 MPlayer Team > mplayer: could not connect to socket > mplayer: No such file or directory > Failed to open LIRC support.
