I have found audio, in general, and pulseaudio, in particular, tricky. I try to divide audio into parts, alsa is one part, pulseaudio another. I believe many software programs use alsa. I believe alsa, in turn, uses pulseaudio. I must add a caveat. I believe programs can be configured to use alsa. I believe some programs can be configured to use pulseaudio, bypassing alsa. I believe some programs can be configured to bypass pulseaudio, and go straight to the hardware device drivers. Assuming your configuration uses alsa, which in turn goes to pulseaudio, I believe you have to look at both alsa and pulseaudio. For alsa, do you have alsa-utils installed? For me, it is rpm -q -i alsa-utils: rsewill@rsewill:~ <2:18> $ rpm -q -i alsa-utils Name : alsa-utils Relocations: (not relocatable) Version : 1.0.22 Vendor: Fedora Project Release : 1.fc12 Build Date: Sat 02 Jan 2010 03:26:02 .... If you this installed, there is a program, amixer, please type amixer When I type amixer, I get the following: rsewill@rsewill:~ <2:16> $ amixer Simple mixer control 'Master',0 Capabilities: pvolume pswitch pswitch-joined penum Playback channels: Front Left - Front Right Limits: Playback 0 - 65536 Mono: Front Left: Playback 15601 [24%] [on] Front Right: Playback 15601 [24%] [on] Simple mixer control 'Capture',0 Capabilities: cvolume cswitch cswitch-joined penum Capture channels: Front Left - Front Right Limits: Capture 0 - 65536 Front Left: Capture 32845 [50%] [on] Front Right: Capture 32845 [50%] [on] "Master" seems to control output volume for me. "Capture" seems to control input from my microphone. For audio output, I want "Front Left" and "Front Right" of "Master" to have a certain volume level, in my case 24%, and be on. I actually control volume by adjusting the volume of "Master". I leave pulseaudio alone once I have it set the way I want it. For my microphone, I control the volume using "Capture". I leave pulseaudio alone once I have it set the way I want it. I believe this is only part of the picture. Alsa, in turn goes to pulseaudio. There is a pulseaudio volume control applet. Do you have pavucontrol installed? It is found in the rpm pavucontrol, for me rpm -q -i pavucontrol yields rsewill@rsewill:~ <2:21> $ rpm -q -i pavucontrol Name : pavucontrol Relocations: (not relocatable) Version : 0.9.10 Vendor: Fedora Project Release : 1.fc12 Build Date: Wed 14 Oct 2009 03:11:07 PM CDT .... When I run this applet, either from the command line, as pavucontrol, or from the menu--it is found as Applications->Sounds and Video-->Pulse Audio Volume Control an applet pops up, with 5 tabs, "Playback","Recording","Output Devices","Input Devices","Configuration" Please look at the "Output Devices" tab, show "All Output Devices", Please make sure the device is not muted--if the device is muted the "Front Left" and "Front Right" lines will be greyed out on a device. Please adjust the volume of this device, as appropriate. For me, I have the volume of my device adjusted to 24% for both "Front Left" and "Front Right". I have not found man pages for pavucontrol or amixer. I can make educated guesses what the tabs for pavucontrol mean, but I would be guessing. You will have different hardware. You may get different devices to examine. Hope you can adapt what I see on my system to what you have.
