I know I might sound stuck on the nodeid theory, but I have built a working audio driver in osx & when I take the nodeid's in the pathmap of the driver (0x14-0x0c-0x02 "hex") which is sending sound to the headphones with the settings it see's in my codecverbs then change the nodeid's to (0x17-0x0f-0x05) it starts sending the sound to the lineout & so on for every other Input/output. So since the driver is working properly its just strange that when I change the "Nodes" to (0x15-0x0d- 0x03) there seems to be no sound going to speakers, & odd Ubuntu also has no output to Internal speakers (not familiar with alsa source yet for comparison).
I'm just wondering if theres a way to rule out the possibility that HP has mapped the internal speakers to non-standard nodes & their windows driver is overriding the chips defaults which are possibly being displayed incorrectly by the bios (I've heard of hp doing something on those lines before). Or that there is special amplification settings for the internal speakers, I did see inside there are 2 sets of wires going to each speaker, (black/white) & (black/red). maybe its just because there are 4 speakers but I would think if its stereo there'd only be one set to each speaker for 2ch. Is it possible their powered & the codec handles their power management? Just sending some ideas for thought, let me know if you think I should do something to test further. -- HP Touchsmart 600-1005xt No sound from Internal Speakers https://bugs.launchpad.net/bugs/597056 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
