Hi, I have made more tests this morning and I have found a constant behavior in my audio system:
1) using the original </etc/modprobe.d/alsa-base.conf> as it was installed with 1.0.21 alsa driver, I obtained this: --> sound from headphones OK --> sound recording with integrated microphone OK --> sound from laptop speakers KO (completely muted) 2) using the original </etc/modprobe.d/alsa-base.conf> as it was installed with 1.0.21 alsa driver, plus the option <options snd-hda-intel model=hp-m4 enable_msi=1>, I obtained this: --> sound from headphones OK --> sound recording with integrated microphone KO (device not active) --> sound from laptop speakers OK I hope this can help ** Description changed: I have installed Ubuntu 9.04 64bit on my laptop HP HDX 18 (details here: http://h10010.www1.hp.com/wwpc/ch/fr/ho/WF06b/321957-321957-3806904-3806906-3806906-3884582-3938575.html) - I have installed the last alsa driver 1.0.20 from a PPA repository just to obtain the sound from the audio card. This because with the default alsa driver 1.0.18 of Jaunty repository the sound don't function. This way I can obtain the right sound from the speakers and with the hear-phones. + I have installed the last alsa driver 1.0.20 from a PPA repository just to obtain the sound from the audio card. This because with the default alsa driver 1.0.18 of Jaunty repository the sound don't function. This way I can obtain the right sound from the speakers and with the headphones. The only part of the sound system of the laptop that don't work so far is the internal stereo microphone that should work with the internal webcam. I have tried with all alsa mixer and pulseaudio options, but the microphone don't work. I can't record nothing but some kind of regular noise. I attach to this bug report some system details and audio system details that I hope can be useful to find a solution. -- Internal Microphone don't work on Laptop HP HDX 18 https://bugs.launchpad.net/bugs/393165 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
