Hi,
I'm having some serious woes while trying to set up audio on my x86_64
(pure 64) LFS build (in the hopes of having all kinds of multimedia
adventures). I'm not to savvy with hardware, so forgive me if the
solution is glaringly obvious to anyone. ALSA and the proper sound card
driver have been built into the kernel (see below).
I'm using the svn version of the BLFS book. In the ALSA Utilities
chapter of BLFS, the "alsactl state" command yields this (my first
indication of a problem):
alsactl: save_state:1163: No soundcards found...
And alsaconf only prints the following:
modinfo: could not find module snd
modinfo: could not find module snd
modinfo: could not find module snd
Error, dialog or whiptail not found.
"gunzip -c /proc/config.gz | grep -i snd" prints the following:
CONFIG_SND=y
CONFIG_SND_TIMER=y
CONFIG_SND_PCM=y
CONFIG_SND_SEQUENCER=y
# CONFIG_SND_SEQ_DUMMY is not set
CONFIG_SND_OSSEMUL=y
CONFIG_SND_MIXER_OSS=y
CONFIG_SND_PCM_OSS=y
CONFIG_SND_SEQUENCER_OSS=y
# CONFIG_SND_RTCTIMER is not set
# CONFIG_SND_VERBOSE_PRINTK is not set
# CONFIG_SND_DEBUG is not set
# CONFIG_SND_DUMMY is not set
...
CONFIG_SND_AC97_CODEC=y
...
CONFIG_SND_INTEL8X0=y (The one labeled under PCI as
"Intel/SiS/nVidia/AMD/ALi AC97 Controller")
The sound card is built in on an NVidia chipset for an Athlon64
processor. From dmesg: #0: NVidia CK804 with ALC850 at 0xd2002000, irq 23
lspci also finds it: 00:04.0 Multimedia audio controller: nVidia
Corporation CK804 AC'97 Audio Controller (rev a2)
I'm really lost on this one and can't seem to find any suggestions for a
solution anywhere. Help would greatly be appreciated, or suggestions of
where to get more information on this kind of problem. I'm not even sure
what kind of problem this is...
Ryan
