After the upgrade everything seemed fine, except for sound. While trying to determine what is wrong I ran alsamixer and got the following error: alsamixer: function snd_ctl_open failed for default: No such device The device /dev/mixer is there and so is /dev/mixer0. lsmod | grep snd output is: snd_pcm_oss 44320 0 snd_pcm 71300 1 snd_pcm_oss snd_timer 22276 1 snd_pcm snd_mixer_oss 17792 1 snd_pcm_oss snd 48228 4 snd_pcm_oss,snd_pcm,snd_timer,snd_mixer_oss soundcore 9568 1 snd snd_page_alloc 9608 1 snd_pcm Ive searched the forums most of today and could not find any solutions. Can anybody help? This is my first post, I hope Ive posted in the correct area. Sorry if not. Thanks in advance! |

Update to my situation: The mixer problem mysteriously went away after a reboot. My current symtoms: If I cat /dev/video > test.mpg, and then ftp file to another linux box, the video and sound are fine. That tells me the ivtv drivers are ok, I would think. If I ftp a recent recorded file via mythtv, then the video is ok, but the sound is barely audible and scratchy. Either way, I cant hear anything on the knoppmyth box when I try to watch these 2 files. Does this point to the kernel upgrade when I went from R5C7 -> R5D1? Something in myth? Thanks, Dave B. |
