The problem with finding a package for an error in the kernel is that the "Choose" option always finds too many options and refuses to give you any . So how can I find a suitable package?
** Package changed: ubuntu => linux (Ubuntu) ** Description changed: The em28xx module is used with a lot of TV and video hardware, and is needed also for the video grabber Terratec Grabster AV350MX. However, with this external, USB connected device the wrong settings are applied, allowing only a (good quality) video picture, but no sound at all. Applying the workaround results in both good picture and good sound. The Terratec Grabster AV350MX (lsusb: 0ccd:0084) has a cheaper sister grabber Terratec Grabby (0ccd:0096) with the same hardware chip Empia EM2860. In the kernel driver file em28xx.h the former is card#68, while the latter is card#67. Using Ubuntu 12.04, 64bit, kernel 3.2.0-24 correctly recognizes the AV350MX, and loads some modules, but then has no sound using mplayer (commands below) , vlc, arecord. Apply these workaround steps to reload em28xx with the settings for the sister card. Thereafter dmesg incorrectly identifies the card as Terratec Grabby, but sound now works in addition to picture: - (insert Grabster and leave inserted) - - sudo rm em28xx + - 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 I verified that the error still exists in kernel 3.4.0-rc6. Could someone help me to "automate" the workaround until this is fixed in the kernel? ** Summary changed: - em28xx incorrectly sets Terratec Grabster AV350MX resulting in no sound -Workaround + em28xx incorrectly sets Terratec Grabster AV350MX resulting in no sound - Workaround provided -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/998143 Title: em28xx incorrectly sets Terratec Grabster AV350MX resulting in no sound - Workaround provided To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/998143/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
