Hey all,
For quite a while now, the internal speaker volume on my Dell Latitude D830 has been very soft. While usually the case can be made to resonate with all mixers at 100%, recently I have noticed a substantial decrease in output.
Figuring this must be caused by a codec mis-configuration, I booted into a working kernel 2.6.27.9-134.fc10.x86_64 and collected a dump from /proc/asound/card0/codec#0. After booting back into my own vanilla kernel from master, I collected another trace. When I was looking through the diff -u of the two dumps, one particular difference seemed notable,
Node 0x11 [Audio Output] wcaps 0xd0c05: Stereo Amp-Out R/L Amp-Out caps: N/A - Amp-Out vals: [0x7f 0x7f] - Converter: stream=5, channel=0 + Amp-Out vals: [0xff 0xff] + Converter: stream=0, channel=0 Power: setting=D0, actual=D0 Delay: 13 samples
Perhaps this is significant? Regardless, I have attached both of the original dumps. Let me know if anything else is needed. Thanks,
- Ben
