|
This should be the best choice of category for this.
I don't have sound on my gentoo which is not good for multimedia. The kernel config should be ok I suspect, but you never know.
It's an intel on board hardware for sound and there is no doubt about the right driver, snd_hda_intel.
I have alsa-utils
| Code: |
idella@gentoo /usr/src $ sudo emerge --search alsa-utils

I run alsaconf which should be quite satisfactory, and I have

I ran alsamixer.
After all this I get an annoying system beep for sound, about 1 per second, which I've never come across before.
Now the bad news, this is a kde 3.5, rather than the latest. Before prompting me to update, I have another current version of gentoo which is fine.
This system is about 20 months old and works fine except for the sound. Kernel is 2.6.26. For my own reasons I've decided to leave this as is.
I emerged the alsa-utils which is a current version, so there is a vague chance that the alsa-utils might be too new for the rest of the system, but I doubt it.
With a music cd in the cd drive, kscd finds the music ok, then plays the tracks but no sound is produced.
I'm confused why there is something wrong since the basics all seem to be in place and are a mirror of the current healthy gentoo.
ny helpers please?

or did you enable pcspkr kernel module (in the "event" section).

pcspkr kernel module
yes
| Code: |
CONFIG_PCSPKR_PLATFORM=y
|
Is that right or wrong for a healthy system?

| Code: | $ zcat /proc/config.gz | grep pcspkr
CONFIG_PCSPKR_PLATFORM=y
CONFIG_INPUT_PCSPKR=y |
There's another possibility: | Code: | | CONFIG_SND_HDA_INPUT_BEEP |
I will try this instead of INPUT_PCSPKR the next time I compile a kernel. |

eh ,yes, well my config has just CONFIG_PCSPKR_PLATFORM, not CONFIG_INPUT_PCSPKR. I don't have CONFIG_SND_HDA_INPUT_BEEP.
How does this help towards procuring sound? Do I turn the above off?
I have 2 separate issues, the beeping, and no sound when invoked.

idella4,
Your kernel looks ok. Lets address the two issues separately - the no sound first.
Your front speakers need to be plugged into the pale green jack socket. Its these we will work with, if you have surround, that will fall into place.
Your sound card | Code: | | nVidia Corporation MCP73 High Definition Audio |
can generate either digital sound or analogue sound but not both at the same time.
To ensure you get analogue sound for you speakers, all the controls with IEC in their names must be muted, that turn off digital, so the card reverts to analogue mode.
Muted is indicated with MM in the box under the slider - not all controls have sliders.
The controls Master and PCM if you have it, must be unmuted [OO] in the box below the sliders, and the sliders set to about 70%.
Test with | Code: | | mplayer -ao alsa /path/to/sound/file |
mplayer will play the sound file given. If it fails, mplayer also gives useful error messages, which is why I picked it for testing. Be sure to post them.
Please post if it fails too - there are a few USE flags you need, which are normally set in your profile.
Moving slowly onto the other part of the problem, where does the beep come from, your speakers or the motherboard sounder that the BIOS beeps as part of its POST ?
