Dotaz: Intel 82801CA/CAM AC97 v IBM T32 - velmi tichy zvuk

[BigWrigley]

Zdravim.

Resim uz asi 3. den problem s nasl. HW: NTB IBM R32, zvukovka onboard Intel 82801CA/CAM. Debian a kernel 2.6.24-3, alsa 1.0.16. Driver je jasny: snd-intel8x0, resp. snd-intel8x0m pro modem cast. Moduly se natahnou, mixery na max, ale zvuk je velmi tichy. Je slyset, jen kdyz v xmms v ekvalizeru dam zesileni na max.

Zkousel jsem google a vsemozne quirks pro AC97, jako parametr k snd-intel8x0 ac97_quirk=1,2, ... Nic z toho nezabira. Pri prehravani pres emulaci oss je to stejne. Pri tom na tomhle nTB mi to kdysi bez problemu fungovalo, hadam, ze se muselo tak od 2.6.8 neco zmenit. S originalnim debian jadrem 2.6.18-6 to nefunguje take.

Samozrejme jsem hledal, problem se obsas vyskytuje, ale zadne rozumne reseni, krome zminenych quirks, jsem nenasel. Ma nekdo nejaky napad? Nebo aspon tip na funkcni USB zvukovku? Diky vsem. Ales

Výstup na sluchátka má hlasitost v pořádku? Pokud ano, mohlo by to být routingem. Vím že indel-hda šváby si každý zapojí trochu jinak, takže třeba u některých Acerů to bylo němé, dokud se nepřidal nový typ modelu do Alsy, který routoval jinak.

[BigWrigley]

Ne, ten je prave velmi tichy. Z repro neni slyset vubec nic.

[R]

Skusal si pohrat sa v alsamixeri s tymi prepinacmi?

[BigWrigley]

Jasne. Nekolikrat. Napr. regulator PCM funguje, funguje i "mute", tedy v ramci te celkove velmi nizke hlasitosti. Jinak nic, zadna zmena.

Jo, a koukam, ze jsme se seknul v titulku, ma to byt IBM R32.

[Jooky (inactive)]

nema ten notebook aj dalsiu na zvukovke nezavislu regulaciu ako moj IBM R51 ? (tlacidla na kb mi menia toto, nie veci v alse)

lukas@lukas ~ $ cat /proc/acpi/ibm/volume
level:          7
mute:           off
commands:       up, down, mute
commands:       level <level> (<level> is 0-15)
lukas@lukas ~ $             

[BigWrigley]

BINGO! Tak tohle me teda nenapadlo. Stacilo sahnout na tlacitka ovladani hlasitosti na ntb. Sice nemam /proc/acpi/ibm a tlacitka hlasitost nereguluji, ale zvuk evidentne ztlumen tlacitkem MUTE. Zkusim jeste juknout do jadra, jestli mi neco nechybi.

Diky moc za spravne nakopnuti!

zdravim,

to co mozna take potrebujete se jmenuje thinkpad-acpi. Modul je v jadrech asi od rady 2.6.22.

Od nejake verse jadra je take snad pridan dalsi mixer nebo cast mixeru specielne pro ovladani specialnimi tlacitky na thinkpadech.

Obcas spolupracuji s vyvojarem modulu. Muzete mi poslat vypis prikazu dmidecode (pokud je treba, tak bez seriovych cisel) prikaz dmidecode > dmidecode a dsdt acpi tabulku cat /proc/acpi/dsdt > dsdt.dat

na email goldenfish at linuxsoft dot cz ?

Udaje o notebooku rady T32 jeste nejsou na wiki o thinkpadech a pomuze to i vyvoji modulu.

Dobry den, ve skutecnosti je to R32 - uklepnul jsem se v titulku. Nicmene vam to vecer poslu, koukal jsem, ze R32 na www.thinkwiki.org take zatim chybi.

neviem ci aj ta verzia je podporovana, ale na mojom R51 celkom dobre funguje toto:

lukas@lukas ~ $ eix -e tpb
[I] app-laptop/tpb

     Installed versions:  0.6.4(15:41:40 11.02.2008)(nls xosd)

lukas@lukas ~ $           

Vecsinu casu mam mixer v alse nastaveny na 71 (master, pcm) a ostatok na 0, hlasitost menim len tlacidlami na booku a ten soft mi zobrazi ako som zmenil hlasitost.
btw funguje to aj na jas, thinklight a cez to sa da namapovat access ibm na nejaku app :o)
btw2. napr aj conky zvlada ukazovat tu hw hlasitost + hromadu dalsich veci z ibm booku
