I didn't like it either, however, the doc file I referred to says this to their defense: "The HD-audio component consists of two parts: the controller chip and the codec chips on the HD-audio bus. Linux provides a single driver for all controllers, snd-hda-intel. Although the driver name contains a word of a well-known hardware vendor, it's not specific to it but for all controller chips by other companies. Since the HD-audio controllers are supposed to be compatible, the single snd-hda-driver should work in most cases. But, not surprisingly, there are known bugs and issues specific to each controller type. The snd-hda-intel driver has a bunch of workarounds for these as described below." > try this: > > grep -i snd /usr/src/linux/.config > > I would rather go for an older nvidia audio module than an intel one. > $ grep -i snd /usr/src/linux-2.6.32-gentoo-r3/.config 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 is not set 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 # CONFIG_SND_HRTIMER is not set # CONFIG_SND_DYNAMIC_MINORS is not set CONFIG_SND_SUPPORT_OLD_API=y # CONFIG_SND_VERBOSE_PROCFS is not set # CONFIG_SND_VERBOSE_PRINTK is not set # CONFIG_SND_DEBUG is not set CONFIG_SND_VMASTER=y CONFIG_SND_DMA_SGBUF=y CONFIG_SND_RAWMIDI_SEQ=m CONFIG_SND_OPL3_LIB_SEQ=m # CONFIG_SND_OPL4_LIB_SEQ is not set # CONFIG_SND_SBAWE_SEQ is not set CONFIG_SND_EMU10K1_SEQ=m CONFIG_SND_MPU401_UART=m CONFIG_SND_OPL3_LIB=m CONFIG_SND_VX_LIB=m CONFIG_SND_AC97_CODEC=m CONFIG_SND_DRIVERS=y # CONFIG_SND_PCSP is not set # CONFIG_SND_DUMMY is not set # CONFIG_SND_VIRMIDI is not set CONFIG_SND_MTPAV=m CONFIG_SND_SERIAL_U16550=m CONFIG_SND_MPU401=m # CONFIG_SND_AC97_POWER_SAVE is not set CONFIG_SND_SB_COMMON=m CONFIG_SND_SB16_DSP=m CONFIG_SND_PCI=y CONFIG_SND_AD1889=m CONFIG_SND_ALS300=m CONFIG_SND_ALS4000=m CONFIG_SND_ALI5451=m CONFIG_SND_ATIIXP=m CONFIG_SND_ATIIXP_MODEM=m CONFIG_SND_AU8810=m CONFIG_SND_AU8820=m CONFIG_SND_AU8830=m CONFIG_SND_AW2=m CONFIG_SND_AZT3328=m CONFIG_SND_BT87X=m # CONFIG_SND_BT87X_OVERCLOCK is not set CONFIG_SND_CA0106=m CONFIG_SND_CMIPCI=m CONFIG_SND_OXYGEN_LIB=m CONFIG_SND_OXYGEN=m CONFIG_SND_CS4281=m CONFIG_SND_CS46XX=m CONFIG_SND_CS46XX_NEW_DSP=y CONFIG_SND_CS5530=m # CONFIG_SND_CS5535AUDIO is not set # CONFIG_SND_CTXFI is not set CONFIG_SND_DARLA20=m CONFIG_SND_GINA20=m CONFIG_SND_LAYLA20=m CONFIG_SND_DARLA24=m CONFIG_SND_GINA24=m CONFIG_SND_LAYLA24=m CONFIG_SND_MONA=m CONFIG_SND_MIA=m CONFIG_SND_ECHO3G=m CONFIG_SND_INDIGO=m CONFIG_SND_INDIGOIO=m CONFIG_SND_INDIGODJ=m CONFIG_SND_INDIGOIOX=m CONFIG_SND_INDIGODJX=m CONFIG_SND_EMU10K1=m CONFIG_SND_EMU10K1X=m CONFIG_SND_ENS1370=m CONFIG_SND_ENS1371=m CONFIG_SND_ES1938=m CONFIG_SND_ES1968=m CONFIG_SND_FM801=m # CONFIG_SND_FM801_TEA575X_BOOL is not set CONFIG_SND_HDA_INTEL=m # CONFIG_SND_HDA_HWDEP is not set # CONFIG_SND_HDA_INPUT_BEEP is not set # CONFIG_SND_HDA_INPUT_JACK is not set # CONFIG_SND_HDA_PATCH_LOADER is not set CONFIG_SND_HDA_CODEC_REALTEK=y CONFIG_SND_HDA_CODEC_ANALOG=y CONFIG_SND_HDA_CODEC_SIGMATEL=y CONFIG_SND_HDA_CODEC_VIA=y CONFIG_SND_HDA_CODEC_ATIHDMI=y CONFIG_SND_HDA_CODEC_NVHDMI=y CONFIG_SND_HDA_CODEC_INTELHDMI=y CONFIG_SND_HDA_ELD=y CONFIG_SND_HDA_CODEC_CIRRUS=y CONFIG_SND_HDA_CODEC_CONEXANT=y CONFIG_SND_HDA_CODEC_CA0110=y CONFIG_SND_HDA_CODEC_CMEDIA=y CONFIG_SND_HDA_CODEC_SI3054=y CONFIG_SND_HDA_GENERIC=y CONFIG_SND_HDA_POWER_SAVE=y CONFIG_SND_HDA_POWER_SAVE_DEFAULT=0 CONFIG_SND_HDSP=m CONFIG_SND_HDSPM=m CONFIG_SND_HIFIER=m CONFIG_SND_ICE1712=m CONFIG_SND_ICE1724=m CONFIG_SND_INTEL8X0=m CONFIG_SND_INTEL8X0M=m CONFIG_SND_KORG1212=m # CONFIG_SND_LX6464ES is not set CONFIG_SND_MAESTRO3=m CONFIG_SND_MIXART=m CONFIG_SND_NM256=m CONFIG_SND_PCXHR=m CONFIG_SND_RIPTIDE=m CONFIG_SND_RME32=m CONFIG_SND_RME96=m CONFIG_SND_RME9652=m CONFIG_SND_SONICVIBES=m CONFIG_SND_TRIDENT=m CONFIG_SND_VIA82XX=m CONFIG_SND_VIA82XX_MODEM=m CONFIG_SND_VIRTUOSO=m CONFIG_SND_VX222=m CONFIG_SND_YMFPCI=m CONFIG_SND_USB=y CONFIG_SND_USB_AUDIO=m CONFIG_SND_USB_USX2Y=m CONFIG_SND_USB_CAIAQ=m CONFIG_SND_USB_CAIAQ_INPUT=y CONFIG_SND_USB_US122L=m CONFIG_SND_PCMCIA=y CONFIG_SND_VXPOCKET=m CONFIG_SND_PDAUDIOCF=m CONFIG_SND_SOC=m CONFIG_SND_SOC_I2C_AND_SPI=m # CONFIG_SND_SOC_ALL_CODECS is not set Which one would that be?
