I have a creative USB sound card attached and it will just stop producing any sound after a few hours. It's intermittent and I can't seem to reliably replicate. Ohh, the headphones are plugged in ;) Loaded modules : snd_usb_audio 59809 3 snd_pcm_oss 47609 0 snd_mixer_oss 17216 2 snd_pcm_oss snd_pcm 97993 2 snd_usb_audio,snd_pcm_oss snd_timer 29765 1 snd_pcm snd_page_alloc 9673 1 snd_pcm snd_usb_lib 12097 1 snd_usb_audio snd_rawmidi 26725 1 snd_usb_lib snd_seq_device 8137 1 snd_rawmidi snd 54053 11 snd_usb_audio,snd_pcm_oss,snd_mixer_oss,snd_pcm,snd_timer,snd_rawmidi,snd_seq_device soundcore 9889 2 snd When the sound plays the light on the box flashes indicating there is something being sent by no sound. Reinitialization ( unplugging and plugging in again ) will solve the problem and bring sound back to life but the PS/2 keyboard ceases to operated thus requiring a reboot. The reboot also solved the sound problem. Any tips for diagnosing this? I've checked bugzilla and can't seem to find a matching bug.
