[gentoo-user] Still haveing problems with audio and guvcview
Hi, for my webcam (Nam Tai EE Products Ltd. or OmniVision Technologies, Inc. Sony Playstation Eye) I am using guvcview 1.4.5. The Webcam is attached via usb to my PC. Since the webcams audio device was not listed in the according drop down menu of guvcview I browsed through the kernel (2.6.39 vanilla) config and found, that I forgot to include the usb-audio module. After recompiling and rebooting, guvcview now lists the webcams audio device (but still no sound). Unfortunately it kills any sound when using mplayer, which says: == Opening video decoder: [ffmpeg] FFmpeg's libavcodec codec family Selected video codec: [ffh264] vfm: ffmpeg (FFmpeg H.264) == == Opening audio decoder: [ffmpeg] FFmpeg/libavcodec audio decoders AUDIO: 44100 Hz, 2 ch, s16le, 111.8 kbit/7.92% (ratio: 13970-176400) Selected audio codec: [ffaac] afm: ffmpeg (FFmpeg AAC (MPEG-2/MPEG-4 Audio)) == [AO_ALSA] alsa-lib: pcm_dmix.c:1018:(snd_pcm_dmix_open) unable to open slave [AO_ALSA] Playback open error: No such file or directory [JACK] cannot open server [AO SDL] Samplerate: 44100Hz Channels: Stereo Format s16le [AO_ALSA] alsa-lib: pcm_dmix.c:1018:(snd_pcm_dmix_open) unable to open slave [AO SDL] Unable to open audio: No available audio device DVB card number must be between 1 and 4 AO: [null] 44100Hz 2ch s16le (2 bytes per sample) Starting playback... /dev/audio and /dev/audio1 do exist... cat /proc/asound/cards 0 [CameraB404271 ]: USB-Audio - USB Camera-B4.04.27.1 OmniVision Technologies, Inc.

For mplayer you can force the output to use the proper device in your mplayer.conf Use alsamixer to enable/disable the inputs depending on when you are using them. Maybe your microphone is recording and played back when you watch TV, causing the bad sounds... it's only a guess. :) For testing it might be easier to use aplay and arecord (from media-sound/alsa-utils) since they give you a more explicit choice of ALSA devices. For example aplay -l will list your playback devices, arecord -l will list the input devices. Then you can experiment with them and alsamixer until you find which one works. The alsa-info script will give you all the info about your sound hardware. Probably more info than you care about knowing. :) Good luck, Paul
