Unfortunately I had tried previously with mplayer and using: mplayer -tv driver=v4l2:device=/dev/video1:norm=PAL:chanlist=europe-west tv:// I can see the video without audio, while with: mplayer -tv driver=v4l2:device=/dev/video1:norm=PAL:chanlist=europe- west:alsa=1:adevice=hw.2:audiorate=48000:forceaudio=1:immediatemode=0:amode=1 tv:// mplayer exits immediately with this error: v4l2: current audio mode is : STEREO v4l2: ioctl set format failed: Invalid argument v4l2: ioctl set format failed: Invalid argument v4l2: ioctl set format failed: Invalid argument ALSA lib pcm_hw.c:1429:(_snd_pcm_hw_open) Invalid value for card Error opening audio: Permission denied ALSA lib pcm_hw.c:1429:(_snd_pcm_hw_open) Invalid value for card Error opening audio: Permission denied ALSA lib pcm_hw.c:1429:(_snd_pcm_hw_open) Invalid value for card Error opening audio: Permission denied v4l2: 0 frames successfully processed, 0 frames dropped. and similarly with amode=0 (obviously except for s/STEREO/MONO). In attachment the complete standard output and error for the 2 mplayer runs. Thanks, Nicola
