unable to solve fedora 9 pulseaudio hda_intel sound problem

flashl · 06-29-2008, 08:35 PM

Any help appreciated, been on this for several days. Yesterday, for a brief moment pulseaudio server activated but dropped.

hardware info:

Code:

lspci | grep -i audio

lspci -s 00:1b.0 -vn

cat /etc/modprobe.conf:

Again, thanks for any help.

Ok, pulseaudio server now consistently starts upon bootup or gnome login. The reason the pulseaudio daemon failed to startup was this entry in default.pa:

# Load audio drivers statically
load-module module-alsa-sink sink device=dmix

commenting the module-alsa-sink entry in /etc/pulse/default.pa allows the pulseaudio server to startup.

Now, the soundserver starts but there is no sound. Checking PulseAudio Volume Control-->Output Devices, there are two entries:

1. ALSA PCM on front:0 (STAC92xx Analog) via DMA
2. Simultaneous output to ALSA PCM on front:0 (STAC92xx Analog) via DMA

Selecting any sound app and using PulseAudio Volume Meter shows #1 Output Device in use, but there is no sound.

Following instructions in PerfectSetup, /etc/asound.conf contains:

Code:

pcm.pulse {
type pulse
}

ctl.pulse {
type pulse
}

# Optional, set defaults

pcm.!default {
type pulse
}

ctl.!default {
type pulse
}

Devices at GNOME-->Preferences-->Hardware-->Sound are set to PulseAudio Sound Server

What else am I missing?

This probably is not the best solution, but, I have sound!

Code:

cat /etc/asound.conf
# This following device can fool some applications into using pulseaudio
pcm.dsp1 {
type plug
slave.pcm "pulse"
}

ctl.mixer0 {
type hw
card 0
}

pcm.pulse {
type pulse
}

ctl.pulse {
type pulse
}

# Optional, set defaults

pcm.!default {
type pulse
}

ctl.!default {
type pulse
}

cat /etc/pulse/default.pa
