I have a newish PC with onboard audio and pci card:
Code:
00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 02)
03:02.0 Multimedia audio controller: Cirrus Logic Crystal CS4281 PCI Audio (rev 01)
I know they work because I had them both working under Centos with pulseaudio. 2 movies playing, each sending sound to a different card. Then I upgraded pa and everything broke.
I moved on to Arch and just installed the alsa stuff:
Code:
alsa-firmware-1.0.29-1-any.pkg.tar.xz
alsa-lib-1.0.29-1-i686.pkg.tar.xz
alsa-oss-1.0.28-1-i686.pkg.tar.xz
alsa-plugins-1.0.29-2-i686.pkg.tar.xz
alsa-tools-1.0.29-1-i686.pkg.tar.xz
alsa-utils-1.0.29-1-i686.pkg.tar.xz
alsaplayer-0.99.81-6-i686.pkg.tar.xz
I'm pretty sure I don't need the firmware pkg, but, what the heck. I just want sound.

Seems reasonable.

Does that look right? 2 default devices and 2 sysdefaults?
I'm sure this is a simple config thing. That Intel card output looks pretty fancy for something with only a mic jack and combo lineout/headphone jack. Where's all that extra stuff come from?
when I do 'aplay -D default file.wav' it plays out my pc speaker, that little thing inside the tower that usually never does anything. I guess it's good to know I even have one. So I 'rmmod pcspkr' and it still does it. Odd.
When I go 'aplay -D front file.wav' I get no sound, but this pops up:
Code:
Playing WAVE 'doorslam.wav' : Unsigned 8 bit, Rate 22050 Hz, Mono
aplay: set_params:1233: Sample format non available
Available formats:
- S16_LE
- S32_LE
But no sound from the speakers plugged in. Everything is un-muted and cranked up. I get a bump from the speakers on startup and shutdown when the soundcard is initialized.
Any ideas?
I'm new to alsa. I haven't done anything with any config files. The documentation has left me a bit mystified. My last box still had /dev/dsp. I've read pretty much everything about alsa on the internet over the last few days and still no closer to a solution.
Thank you in advance.
I guess it's some kind of fancy Dell feature. Inside the case just behind the front bezel in the line of airflow to the GPU is this cylindrical object about 1" dia with a circuit board attached. BEEP! BEEP! It's a Dell Beep Model #BB4-QBZY-A04 (C)2001! It has BLKWHTREDGRN harness going to 4pin socket on the MB labeled INT SPKR.
