I didn't care for the way that I did troubleshooting nor the way I
reported what I did, so I did the following:
No Sound in speaker and headphones
commented out "options snd-hda-intel power_save=0" from alsa-base.conf
Here is the contents of alsa-base.conf:
# autoloader aliases
install sound-slot-0 /sbin/modprobe snd-card-0
install sound-slot-1 /sbin/modprobe snd-card-1
install sound-slot-2 /sbin/modprobe snd-card-2
install sound-slot-3 /sbin/modprobe snd-card-3
install sound-slot-4 /sbin/modprobe snd-card-4
install sound-slot-5 /sbin/modprobe snd-card-5
install sound-slot-6 /sbin/modprobe snd-card-6
install sound-slot-7 /sbin/modprobe snd-card-7
# Cause optional modules to be loaded above generic modules
install snd /sbin/modprobe --ignore-install snd $CMDLINE_OPTS && {
/sbin/modprobe --quiet --use-blacklist snd-ioctl32 ; /sbin/modprobe --quiet
--use-blacklist snd-seq ; }
#
# Workaround at bug #499695 (reverted in Ubuntu see LP #319505)
install snd-pcm /sbin/modprobe --ignore-install snd-pcm $CMDLINE_OPTS && {
/sbin/modprobe --quiet --use-blacklist snd-pcm-oss ; : ; }
install snd-mixer /sbin/modprobe --ignore-install snd-mixer $CMDLINE_OPTS && {
/sbin/modprobe --quiet --use-blacklist snd-mixer-oss ; : ; }
install snd-seq /sbin/modprobe --ignore-install snd-seq $CMDLINE_OPTS && {
/sbin/modprobe --quiet --use-blacklist snd-seq-midi ; /sbin/modprobe --quiet
--use-blacklist snd-seq-oss ; : ; }
#
install snd-rawmidi /sbin/modprobe --ignore-install snd-rawmidi $CMDLINE_OPTS
&& { /sbin/modprobe --quiet --use-blacklist snd-seq-midi ; : ; }
# Cause optional modules to be loaded above sound card driver modules
install snd-emu10k1 /sbin/modprobe --ignore-install snd-emu10k1 $CMDLINE_OPTS
&& { /sbin/modprobe --quiet --use-blacklist snd-emu10k1-synth ; }
install snd-via82xx /sbin/modprobe --ignore-install snd-via82xx $CMDLINE_OPTS
&& { /sbin/modprobe --quiet --use-blacklist snd-seq ; }
# Load saa7134-alsa instead of saa7134 (which gets dragged in by it anyway)
install saa7134 /sbin/modprobe --ignore-install saa7134 $CMDLINE_OPTS && {
/sbin/modprobe --quiet --use-blacklist saa7134-alsa ; : ; }
# Prevent abnormal drivers from grabbing index 0
options bt87x index=-2
options cx88_alsa index=-2
options saa7134-alsa index=-2
options snd-atiixp-modem index=-2
options snd-intel8x0m index=-2
options snd-via82xx-modem index=-2
options snd-usb-audio index=-2
options snd-usb-caiaq index=-2
options snd-usb-ua101 index=-2
options snd-usb-us122l index=-2
options snd-usb-usx2y index=-2
# Ubuntu #62691, enable MPU for snd-cmipci
options snd-cmipci mpu_port=0x330 fm_port=0x388
# Keep snd-pcsp from being loaded as first soundcard
options snd-pcsp index=-2
# Keep snd-usb-audio from beeing loaded as first soundcard
options snd-usb-audio index=-2
#options snd-hda-intel power_save=0
rebooted and sound came on for a few seconds.
uncommented options snd-hda-intel power_save=0
rebooted no sound
commented out snd-hda-intel power_save=0
added options snd-hda-intel model=auto
rebooted no sound
commented out options snd-hda-intel model=auto
added options snd-hda-intel model=alc295
rebooted a garbled sound lasting a second or so
commented out options snd-hda-intel model=alc295
so now there are no snd-hda-intel options in alsa-base.conf
rebooted no sound
copied snd-hda-intel.conf back into /etc/modprobe.d snd-hda-intel.conf contains
"options snd-hda-intel model=auto
rebooted and have continuous sound in both speakers and headphones
rebooted and still have continuous sound in both speakers and headphones
go figure
