Update to comment #14 above. I can watch the status of the GPIO pin noted above on the code by using this command :
cat /proc/asound/card0/codec#3 | grep 'IO\[0\]' If I boot with no speakers plugged in, and then plug into the green jack, I get normal sound and GPIO IO[0] data=1. If I then plug and unplug the front panel headphone jack, the sound on the speakers goes low and the GPIO IO[0] data=0. If I can figure out how to set / reset that data value it seems like I should be able to reset the speaker volume question i,e, it looks like the driver is setting that wrong on boot based on speakers being present or not. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1041322 Title: Very low sound on HP p7-1227c To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1041322/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
