Description of problem: Automatic detection of the sound card did not work on an Acer Aspire 3002LCi with the latest rawhide, either as part of the install (firstboot, I believe?), or when system-config-soundcard was run after the install was complete. Version-Release number of selected component (if applicable): system-config-soundcard-1.2.16-2 (not sure what else you need) How reproducible: Always Steps to Reproduce: 1. Run system-config-soundcard, and hit the play button to test the sound 2. No sound comes out, and when you tell it so after it asks, it creates a log file which I will attach. Actual results: No sound. Expected results: Sound should work. Additional info:

Everything looks fine, you can check some mixer settings (you should use alsamixer utility) like "External amplifier" and so on...
Ok, that's interesting. Why would having the volume showing up in the middle of the volume level setting not have any sound? I'd not tried upping the volumne, since I didn't expect mid-point to equal silent. Is this something you would be working on, or does it need reassigning?
(happens on a fujitsu lifebook, too)
Just do what I ask you for...
I have no idea how to use the mixer utility you suggested I use, so that's rather difficult to do. Starting it works, but I don't know what keystrokes to use to actually do anything.
If you open the graphical version of the mixer program, while system-config-soundcard is up, and move the volume slider of the s-c-s, it moves both the Master and the PCM input sliders in the volume control window. It should be only affecting the Master one, like the volume button on the panel does. I suspect that this inadvertant association with both Master and PCM is where the problem is coming from. (this is also true if one watches the behavior in alsamixer, which I can check without knowing the necessary keystrokes)
alsamixer is a command line utility, run it from a terminal. External amplifier is a switch (not adjustment) and you can check some other switches, too.
Yes. I ran it. However, starting it is not the same as having any idea how to interact with it once it's been started. I have no idea what you want me to _do_ with it once it's started, and I cannot figure out which switch to use to get the external amplifier (the man page mentions nothing about that). Do you want the value of the external amplifier? Something else? And - is running it actually useful at this point, considering what I found in comment #7? Additionally, have you checked if this is happening on machines you have locally, with rawhide from both two days ago and yesterday? I suspect that it likely is, and doesn't actually require you to be trying to have me debug it via bugzilla.
Use the 'm' key to mute/unmute some channel. I don't have your hardware so there isn't any other way how I can do something with this. btw. everything looks fine so I think the problem can be only with mixer settings. It's very hardware-specific problem and on my box everything works fine, of course.
I'm skeptical that it's a question of muting and unmuting, since increasing the volume from the midpoint of the slider in s-c-s _does_ make the sound audible. Also, changing the mute setting has no effect (it was not set to mute initially, if nothing else), which is something I'd already checked with the graphical mixer tool that I did know how to use. You have verified that there isn't some code somewhere accidentally causing s-c-s's volume slider to be affecting more than one input source? The Acer has it affect both Master and PCM, and the Fujitsu has it affecting both the Volume and CD.
s-c-s's volume slider has to affect all available volume controls because I can't tell which slider exactly affect your hardware configuration (if you can use headphones I have to increase headphone control, if you use some external speakers, I have to increase these). It's a general problem with ALSA mixer and I'm afraid that nobody from RH can solve it...
Hmm. It doesn't seem to be affecting all of them, actually. And I'm fairly sure that there are cases where there is any sound at all when one hasn't yet touched the volume slider. So perhaps it's not this, although it certainly seemed to be. So, keeping in mind that nothing was muted, any other suggestions as to what I should look at?
There can be a bug with "no sound w/o touching any volume slider in s-c-s". You can reproduce this bug simply - remove /etc/asound.state, reboot your box and run s-c-s. All channels are muted after boot, s-c-s should adjust volume to 60% for all playback channels and sound should be audible w/o touching the slider...
I'm sorry, you need to unload all sound modules before deleting /etc/asound.state. You can use modprobe for it: # modprobe -r snd_intel8x0 # modprobe -r snd_intel8x0m if modprobe complains to using this modules, switch to runlevel 3 first: #init 3 and check modprobe again. Then you can delete /etc/asound.state and reboot your box.
Are you telling me that you can now reproduce this? If so, then I'm not sure why you're telling me how to do so, since I can't actually fix the problem. :) If you're asking if this is the same problem, then yes, it looks like the same thing.
You're close. As you said: "And I'm fairly sure that there are cases where there is any sound at all when one hasn't yet touched the volume slider. So perhaps it's not this, although it certainly seemed to be." So I told you how you could check it. I repeat again I can't reproduce this bug, it works fine for me and if I should to fix it I need some feedback.
