    Hi,

    I use alsa for sound-handling and everytime when an application try to
    access the soundcard while an other application is already using the
    soundcard I get an error message, that /dev/dsp can't be access. I use an
    IBM Thinkpad R51 with Intel sound-chip. lspci | grep audio shows:

    0000:00:1f.5 Multimedia audio controller: Intel Corp. 82801DB/DBL/DBM
    (ICH4/ICH4-L/ICH4-M) AC'97 Audio Controller (rev 01)

    I use a 2.6.12.5 kernel with the following sound-configuration:

    #
    # Sound
    #
    CONFIG_SOUND=y

    #
    # Advanced Linux Sound Architecture
    #
    CONFIG_SND=m
    CONFIG_SND_TIMER=m
    CONFIG_SND_PCM=m
    CONFIG_SND_SEQUENCER=m
    CONFIG_SND_SEQ_DUMMY=m
    CONFIG_SND_OSSEMUL=y
    CONFIG_SND_MIXER_OSS=m
    CONFIG_SND_PCM_OSS=m
    CONFIG_SND_SEQUENCER_OSS=y
    # CONFIG_SND_VERBOSE_PRINTK is not set # CONFIG_SND_DEBUG is not set

    #
    # PCI devices
    #
    CONFIG_SND_AC97_CODEC=m
    CONFIG_SND_INTEL8X0=m

    Best Regards
    Sebastian Noack
