Is the problem with ALSA Driver or Kernel?
HI there,
Some time ago my HP laptop running a Conexant CX20549 (Venice) Intel driver was running well under ALSA driver 1.0.14. This included the muting of on board speakers when external speakers or headphones where connected through he jacks on the front of the laptop. Also the touch function switches (blue LED type - I don't know there official title)also worked. I could cut the sound and increase/decrease the volume using them. Perfect.
Since then there has been upgrades of both the kernel and the ALSA drivers. I am currently running Mint, built on Ubuntu. I have limited sound functionality now since the kernel and driver upgrades. I'm running the latest ALSA driver.
What I don't understand is this: Has the driver regressed (seems unlikely) or has Ubuntu or kernel developers stuffed up by leaving something out of the the kernel or tampering with it?
I'm not even sure the question is correct. Maybe the kernel is okay but it could be that the ubuntu team have fiddled with something. I don't know.
Since the problem seems to manifest itself with other distros then I suspect that it may be a kernel or driver. (Do a search on intel sound problems in Linux an you will see what I mean).
Sorry to be long winded, but I'm perplexed by this problem. Why would someone undo something that works perfectly?
Regards
John
