Trying to get sound working on TinyCore 5, 64-bit kernel, 32-bit
userspace with a Haswell i5-4690 CPU and an Asus H97M-Plus
motherboard. My primary need is at least one channel of audio
output from VLC.
Kernel modules appear loaded. "aplay -l" and "aplay -L" show one
card, ALC887-VD. Alsamixer appears to show an HDMI device with
no controls and another device (ALC-887, I think) with controls.
I unmuted and turned up the gain on master on that second device
in order to get any sound output. Oh, and with aplay and a WAV
file, I have to use "plughw:1", because "hw:1" refused to do
single channel.
With aplay on a WAV file, I get scratchy sounds (similar to
pulsed white noise or someone scratching fingernails on a
microphone screen) out of the headphone jack.
Googling didn't find anything that appeared relevant.
Where could I find whether that kernel (3.8.13) supports Haswell
HDMI audio and/or the H97M's audio?
Any pointers to tricks to maybe get the existing sound devices
working?
Buying another sound card is acceptable if necessary. Any
suggestions for something < US$50 that is old enough that is sure
to work with the 3.8.13 kernel? It will be feeding a church PA
system but studio-quality sound is not necessary.
Thanks in advance,
Robert
