Hi all,
I've got sound problems in my HP Pavilion dv4-1125br. The sound card is a Intel 82801I with the IDT 92HD71B7X codec. Sound works ok, including the internal mic and external mic jack, but I still have a couple of problems.
The main problem is that I don't have jack sense in the headphone jack. Headphones do not work and I'm unable even to make them work manually through the mixer. This machine got two headphone jacks in front and none of them works. I've tested it since alsa-driver 1.0.17 and it has never worked.
The other problem is that the speaker volume is low. Even if I increase all available mixer controls (PCM and Master), the volume is still tiny. This is a regression. In alsa-driver 1.0.17 (Fedora 10, kernel 2.6.27.21) the volume is ok, the problem appeared sometime after that and alsa-driver 1.0.18a (Fedora 11 beta, kernel 2.6.29.1). One thing I noticed between these versions is the disappearance of the Front mixer control present in 1.0.17. Maybe that is the cause of the problem.
I've tried all models available to my codec and none of them solved the issue. Actually, all of them seemed to created other problems. The no model version seems the best right now.
I'm attaching the alsa-info output for the Fedora 10 and Fedora 11 beta configurations.
I've tried to download and compile the alsa-driver snapshot, but the compilation failed early on with an a patch failure in my kernel 2.6.29.1 system.
Abraços, Gustavo
