    sounds disappearing

    Sometimes after I have restart my computer the sounds won't work, sometimes they do. When they don't work this is what I get:

    $ aplay /usr/share/sounds/phone.wav
    ALSA lib pcm_dmix.c:819snd_pcm_dmix_open) unable to open slave
    aplay: main:544: audio open error: Device or resource busy

    # aplay -l
    **** List of PLAYBACK Hardware Devices ****
    card 0: I82801DBICH4 [Intel 82801DB-ICH4], device 0: Intel ICH [Intel 82801DB-ICH4]
    Subdevices: 0/1
    Subdevice #0: subdevice #0
    card 0: I82801DBICH4 [Intel 82801DB-ICH4], device 4: Intel ICH - IEC958 [Intel 82801DB-ICH4 - IEC958]
    Subdevices: 1/1
    Subdevice #0: subdevice #0

    I have the same problem with two computers with different sound cards (other is running previous version of kubuntu).

    Re: sounds disappearing

    now I know what's the problem but I don't know how to fix it.

    Only one program can use /dev/dsp at time. E.g. if I have last.fm player running
    other programs can't use sound device. I wonder why there is not any sofware mixing
    running :

    lsof /dev/dsp shows empty. Should there be artsd or something...
