BTW the labels meaning in alsamixer seem not to fit too well, maybe because this HDA/codec couple are way too flexible and dynamically reconfigurable.. (and the alsa driver can't still cope so well) With standard 1.0.17 driver, with regard to mixer status, internal speakers (IS) and headphones (HP), this is what i can say (various test) from left to right in Alsamixer: * there's both music on HP and IS * Master slider control both (IS & HP) Audio Levels * Headphone slider control just HP level * Headphone Mute toggle mute BOTH IS & HP when OFF (!) * PCM slider control level for both HP & IS (during mp3 player) * Front slider control level just for IS! * Analog Loopback toogle controls the IS (works when OFF!) * Analog Loopback 2 toogle controls the HP (works when OFF!) * the only HP jack working (there are two in this Dell Studio) is the middle one! * the other HP jack near the front of the laptop (HP2) doesn't work * if i plug a HP in the HP2 jack the IS quit the audio playing (if i unplug, the IS restart) * Analog Loopback 1 toggle doesn't do nothing at all (neither for IS, nor for HP and HP2) So much is still to be checked and worked on, like: 1. works with the original debian kernel alsa driver? don't know. i zapped that stuff during alsa ugrade so don't have the time to come back. maybe some one can tell us. 2. are the Mics (internal near webcam and Jack) working? it's easy to test, some day, when i'll try Skyp! :-) 3. why the second HP (HP2) doesn't work? need to investigate 4. can we (should we) have auto mute for IS when HP is inserted? maybe it can be done at an user preference level! 5. can we have digital output (SPDIF?) from one of the HP ports? (nice to have!) i made some upgrade on this page, with some stuff also about the "other Os driver", could be helpful get some help from their .ini file: http://www.avalpa.com/assets/andrea/studio15/debian_on_dell_studio15.html that's all for now. i'm quite happier, now sorry again for the noise. bye andrea venturi --------------050804090005090505010209 Content-Type: text/x-vcard; charset=utf-8; name="a_venturi.vcf" Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename="a_venturi.vcf" begin:vcard fn:Andrea Venturi n:;Andrea Venturi org:Avalpa Digital Engineering SRL adr;dom:;;Via dell'Arcoveggio 49/5;Bologna;BO;40129 email;internet:a.venturi@avalpa.com title:CEO tel;work:+39 0514187531 tel;cell:+39 3477142994 url:www.avalpa.com version:2.1 end:vcard --------------050804090005090505010209 Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ Alsa-devel mailing list Alsa-devel@alsa-project.org http://mailman.alsa-project.org/mailman/listinfo/alsa-devel --------------050804090005090505010209--
