Kopiena, kas lieto Linux oper\u0113t\u0101jsist\u0113mu uz kl\u0113pjdatoriem Lenovo Legion Pro 7 (mode\u013ca numurs 16IAX10H), ir non\u0101kusi l\u012bdz paciet\u012bbas gali\u0146am. \u0160o ier\u012b\u010du ieb\u016bv\u0113tie ska\u013cru\u0146i, lietojot Linux, atska\u0146o ska\u0146u bez j\u016btamiem basiem \u2013 t\u0101 ir pliekana un klusa, radot iespaidu, ka str\u0101d\u0101 tikai augstas frekvences ska\u013cru\u0146i (t\u012bteri), nevis visa akustisk\u0101 sist\u0113ma. Lai atrisin\u0101tu \u0161o kaitino\u0161o probl\u0113mu, lietot\u0101ji apvienoju\u0161ies un izsludin\u0101ju\u0161i iev\u0113rojamu atalgojumu \u2013 2000 ASV dol\u0101rus \u2013 ikvienam, kur\u0161 sp\u0113s nodro\u0161in\u0101t pilnv\u0113rt\u012bgu ska\u0146as kvalit\u0101ti Linux vid\u0113 uz \u0161iem portat\u012bvajiem datoriem.<\/p>\n
Daudzveid\u012bgi ziedojumi un glob\u0101ls atbalsts<\/p>\n
\u0160\u012bs iniciat\u012bvas dal\u012bbnieki ir sav\u0101ku\u0161i iespaid\u012bgu summu. S\u0101kotn\u0113jais organizators ziedojis 500 dol\u0101rus, bet cits kopienas loceklis pievienojis v\u0113l 1000 dol\u0101ru. Papildus \u0161iem lielajiem ieguld\u012bjumiem biju\u0161i ar\u012b maz\u0101ki, bet noz\u012bm\u012bgi ziedojumi \u2013 200, 70 un 30 dol\u0101ru apm\u0113r\u0101. Tas liecina par probl\u0113mas pla\u0161o izplat\u012bbu, jo ziedojumi pl\u016bdu\u0161i no da\u017e\u0101diem pasaules nost\u016briem: Francijas, Austr\u0101lijas, V\u0101cijas un Nikaragua. \u0160\u0101da glob\u0101la atsauc\u012bba uzsver, cik daudzus lietot\u0101jus ir sk\u0101rusi \u0161\u012b ska\u0146as probl\u0113ma.<\/p>\n
Tehnisk\u0101 probl\u0113mas b\u016bt\u012bba: nesader\u012bba un nepietiekama konfigur\u0101cija<\/p>\n
Probl\u0113mas sakne mekl\u0113jama ska\u0146as komponentu identific\u0113\u0161an\u0101 un konfigur\u0101cij\u0101. Ofici\u0101li Lenovo Legion Pro 7 (16IAX10H) ir apr\u012bkots ar Realtek ALC3306 audio kodeku. Ta\u010du, lietojot Linux, tas tiek identific\u0113ts nepareizi \u2013 k\u0101 ALC287 ar apak\u0161sist\u0113mu 17aa:3906. \u0160\u012b neatbilst\u012bba liek oper\u0113t\u0101jsist\u0113mas kodolam (kernel) izmantot visp\u0101r\u0113ju ska\u0146as profilu, nevis tam paredz\u0113to specializ\u0113to profilu. Rezult\u0101t\u0101 ska\u013cru\u0146i nesp\u0113j atska\u0146ot zemas frekvences, radot min\u0113to pliekano ska\u0146u. Detaliz\u0113t\u0101ka izp\u0113te atkl\u0101jusi, ka Legion Pro 7 izmanto “gudros” pastiprin\u0101t\u0101jus Awinic AWDZ8399, kas savienoti ar kodeku caur I2C interfeisu (adrese 0x34 un 0x35). Lai gan Linux sist\u0113m\u0101 past\u0101v draiveris snd_soc_aw88399, kas veiksm\u012bgi iel\u0101d\u0113jas, tr\u016bkst cie\u0161\u0101kas integr\u0101cijas ar Realtek kodeku. Tas ir galvenais iemesls, k\u0101p\u0113c visa audio sist\u0113mas topolo\u0123ija nedarbojas optim\u0101li.<\/p>\n
Draiveru un konfigur\u0101cijas izaicin\u0101jumi<\/p>\n
K\u0101 tehniski izpau\u017eas \u0161\u012b probl\u0113ma? SOF (Sound Open Firmware) draiveri var iel\u0101d\u0113t, ta\u010du tas pievieno visp\u0101r\u012bgo ma\u0161\u012bnas draiveri (machine driver) skl_hda_dsp_generic. \u0160\u012b pieeja atbalsta tikai standarta HDA (High Definition Audio) datu pl\u016bsmu un nesp\u0113j darboties ar I2C pastiprin\u0101t\u0101jiem. Tr\u016bkums ir ar\u012b SOF firmware pakotn\u0113 \u2013 tur nav atrodamas nepiecie\u0161am\u0101s topolo\u0123ijas konfigur\u0101cijas failu, piem\u0113ram, sof-arl-alc287-aw88399.tplg.
