I verified that the error still exists in kernel 3.4.0-rc6. WORKAROUND: Insert Grabster and leave inserted. Execute at a terminal: sudo rmmod em28xx sudo modprobe em28xx card=67 Now enjoy video with sound with (PAL video, video on /dev/video0, sound on alsa hw:1,0): mplayer tv:// -tv driver=v4l2:width=720:height=576:outfmt=uyvy:device=/dev/video0:input=0:fps=25:alsa:amode=1:forcechan=2:audiorate=48000:adevice=plughw.1,0:forceaudio:immediatemode=0 -ao sdl,alsa or record to file with (1 minute of uncompressed video/sound): mencoder tv:// -tv driver=v4l2:width=720:height=576:device=/dev/video0:input=0:fps=25:alsa:amode=1:forcechan=2:audiorate=48000:adevice=plughw.1,0:forceaudio:immediatemode=0 -oac copy -ovc copy -o myvideofile -endpos 00:01:00 An insight to the work around is the Terratec Grabster AV350MX (lsusb: 0ccd:0084) is similar to the Terratec Grabby (0ccd:0096) with the same hardware chip Empia EM2860. Also, in the kernel driver file em28xx.h the former is card#68, while the latter is card#67. --- AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24.
