Some additional information: 1. I don't have pulseaudio installed.
2. I use my dell d830 in conjunction with a docking station from dell. And so I have two headphone jacks in my system. One is build in the notebook and one is build in the docking station. Maybe it is important, but I never had problem with the headphone jacks in the docking station. This jack is married with the IEC958 switch in the alsa- mixer. And it is not possible to control this headphone jacks with the master control in the alsa-mixer. 3. Since the update from kernel 2.6.26-9 to 2.6.26-11 the internal headphone jacks seems to work a little bit. I got sound through the headphone but the driver is not really clean. Some devices now are missing in the alsa-mixer and the master control has a own live. It is not possibly to decrease the sound level. If I to the this, the sound increase like from ghost hand. 4. For both kernels, 2.6.26-9 and 2.6.26-11, I can solve the problem with the alsa driver 1.0.19 but not with 1.0.18 (both from linuxant). Furthermore the older kernel 2.6.24 (from Ubuntu 8.04) works without problems on Ubutu 8.10. And this kernel work fine with alsa-driver 1.017 (from linuxant) to. I think the problem is contained in a change from alsa 1.0.17 to 1.0.18. And I can remember to read an entry in a change look from alsa project about a change in a initialization sequence of the stac92xx. Unfortunately I can't find this entry again. Maybe the analog ports of the stac92xx are note used in the same manner on a dell notebook as on a gateway notebook. And maybe a chance in alsa 1.019 only fix issues in a configuration of stac92xx like in a dell systems. -- SigmaTel STAC9205: Headphone Jack Not Working https://bugs.launchpad.net/bugs/306755 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
