Description Edwin Zhai 2011-02-21 18:58:28 UTC 
To support audio from guest, we exported ac97&es1370 emulated sound card and enabled oss/also host driver. But linux guest need install proper driver: snd_intel8x0 & snd_ens1370.

To enable them,
Sound Card Support ==>
Advanced Linux Sound Architecture ==>
*Sequence support
*OSS mixer
*OSS PCM
PCI sound device ==>
*(Creative) Ensoniq audiopci 1370
*Intel/SiS/nVidia/AMD/ALI ac97 controller

Thanks,
edwin

Bruce,

I have tested following config, which enables qemu sato image with sound support. Pls. add them in your qemu x86/x86_64 kernel config, and mark this bug as fixed then.

==============================
CONFIG_SOUND_OSS_CORE=y
CONFIG_SOUND_OSS_CORE_PRECLAIM=y
CONFIG_SND_RAWMIDI=m
CONFIG_SND_SEQUENCER=y
CONFIG_SND_OSSEMUL=y
CONFIG_SND_MIXER_OSS=y
CONFIG_SND_PCM_OSS=y
CONFIG_SND_PCM_OSS_PLUGINS=y
CONFIG_SND_SEQUENCER_OSS=y
CONFIG_SND_RAWMIDI_SEQ=m
CONFIG_SND_AC97_CODEC=m
CONFIG_SND_ENS1370=m
CONFIG_SND_INTEL8X0=m
CONFIG_AC97_BUS=m
