Public bug reported:
Many multimedia applications will not work into Maverick. The problem is the
total absence off oss-emu for alsa.Into the now latest 2.6.35-21 generic core.
There is no way around to solve problems as long that the basic generic kernel
compilation does not include oss.
Currently the last maverick generic kernel config has about oss
CONFIG_SOUND=m
# CONFIG_SOUND_OSS_CORE is not set
CONFIG_SND=m
CONFIG_SND_TIMER=m
CONFIG_SND_PCM=m
CONFIG_SND_HWDEP=m
CONFIG_SND_RAWMIDI=m
CONFIG_SND_JACK=y
CONFIG_SND_SEQUENCER=m
CONFIG_SND_SEQ_DUMMY=m
# CONFIG_SND_MIXER_OSS is not set
# CONFIG_SND_PCM_OSS is not set
# CONFIG_SND_SEQUENCER_OSS is not set
This should be :
CONFIG_SOUND=m
CONFIG_SOUND_OSS_CORE=y
CONFIG_SOUND_OSS_CORE_PRECLAIM=y
CONFIG_SND=m
CONFIG_SND_TIMER=m
CONFIG_SND_PCM=m
CONFIG_SND_HWDEP=m
CONFIG_SND_RAWMIDI=m
CONFIG_SND_JACK=y
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_PCM_OSS_PLUGINS=y
CONFIG_SND_SEQUENCER_OSS=y
I do now of course that maverick is still into beta fase, But for audio
to work fine for all applications It's just a requirement to have those
oss modeles in. also having /dev/mixer /dev/dsp is very important. And
those are only available if snd_pcm_oss.ko and snd_mixer_oss.ko are
present and probably a lot of other ones as well.
Hoping that those oss emu and so for alsa will be present into the next
update of kernel
