snd_hda_intel + waikiki chip + hp dv8230 us = extreme extreme frustration
I'm at my wits end with this stupid laptop.
My latest annoyance deals with the inability to record using my laptop's sound card in linux without rebooting all the way into windows. I've upgraded to every version of alsa that has released, and each one has been worse than the currently patched 1.0.14 rc3 that I have now. The one I have now works fine for sound output, but when I record, I get a very noisy high pitched screech overtop all of the audio, plus a very strange looking waveform in audacity. In fact, the unusual shape of the waveform can be a clue as to whats wrong with the capture code in the driver.
I've tried applying numerous patches I've found online to my existing setup, including
which everyone claims to fix the microphone problem. My only problem is that file is now no longer available. I tried a file conexant-test19a.patch which used to be offered on the same site but its changes did not fix my recording problem.
Any advice from the audio programming experts here will be useful.
My laptop model is hp dv8230us and my card is Conexant CX20551 (Waikiki)
Please don't ask me to do menial thinks like check kmix/alsamixer, run alsaconf, or upgrade to the latest alsa. I also cannot apply patches against the latest alsa as its version of snd-hda-intel actually sets up volume sliders incorrectly for my laptop. I'm not even sure how I got the version I'm using anymore, but I'd be glad to send an expert my code if they want to see it.
