The mixer is NOT muted, and all the pots are open. An audio source is plugged into the motherboard INPUT jack, and amplified speakers are plugged into the motherboard LINE OUT jack.
As soon as Debian starts (but not before), the audio source is heard from the speakers, so ALSA is functioning. But when I attempt to play a .wav file (already on the hard drive) using aplay, no sound is heard.
...
I'm lost as to why a wav won't play, unless some of the modules aren't loaded. What do you get with lsmod?
Per the request of Andrea, I posted to this list the output of lsmod.
Have you run alsaconf, which writes the appropriate stuff for ALSA in modules.conf?
I previously ran alsoconf, but I ran it again today, and it did not correct the problem.
With recording, is the line input slider in alsamixer set for capture?
Where, pray tell, is the "line input slider"? And how do I set it for capture?
From the Gnome2 desktop main menu, I selected:
APPLICATIONS --> DEBIAN MENU --> SOUND --> MIXERS --> ALSAMIXERGUI
which displays a mixer panel labeled:
card: Intel 82801DB-ICH4 chip: Analog Devices AD1980
(1) On the FIRST horizontal row, there are what appear to be pairs of speaker icons, which change in colour and appearance to indicate mute or active.
(2) On the SECOND horizontal row, there are pairs of circles, which change from white to red when clicked, to indicate selection of the item. Clicking on a new item deselects the previously-selected item. I'm not sure what these circles indicate. They appear only on the items labeled LINE, CD, MIC, PHONE, and AUX. When an item is selected by clicking on the corresponding circle pair, the corresponding tab in the fifth horizontal row becomes shaded.
(3) On the THIRD horizontal row are the level sliders (potentiometers).
(4) On the FOURTH horizontal row are padlock symbols; when clicked, they toggle between locked and unlocked, to indicate binding together the left and right channels.
(5) On the FIFTH horizontal row are labeled tabs:
MASTER MASTER PHONO MASTER SURROUND PCM SURROUND CENTER LFE * LINE * CD * MICROPHONE MICROPHONE BOOST MICROPHONE SELECT VIDEO * PHONE IEC958 IEC958 PLAYBACK AC97 IEC958 PLAYBACK SOURCE * AUXILIARY CAPTURE MIX MIX MENU EXTERNAL AMPLIFIER POWER-DOWN
Clicking on a tab selects the tab and deselects the previously-selected tab, but the corresponding circles on the second horizontal row are not affected.
The D845PEBT2 motherboard has the following rear-panel audio connectors:
FRONT L/R OUTPUT REAR L/R OUTPUT CENTER/LFE OUTPUT LINE INPUT LINE OUTPUT MICROPHONE INPUT RCA S/PDIF (OUTPUT ONLY) OPTICAL S/PDIF (OUTPUT ONLY)
The D845PEBT2 motherboard has the following on-board audio connectors:
ATAPI CDROM
There is only a makeshift man page for alsamixergui, created by the Debian maintainer.
