V Ubuntu 8.04 ide velmi potichu mikrofon. Ked si ho dam priamo k ustam a normalne nahlas hovorim tak ide na cca 10% (nahral som to v audacious a tam po normalizacii bola kvalita ok takze s tym problem nebude). V alsamixer v capture aj playback mam vsetko na maxime. Presiel som web ale nic moc som nenasiel, len ze zapnut mic boost ale ten tam v alsamixeri nevidim. Neda sa nejako povedat aby pausalne vynasobil vstup mikrofonu 10x ? To by kompletne vyriesilo moj problem.

Zvuk by urcite sel nejak automaticky zesilit, bohuzel by to i 10x zesililo sum a tudiz to moc pouzitelny nebude...
Prave ze toto je presne co potrebujem. Nahral som to v audacity a 10x zvysil hlasitost a zvuk je kristalovo cisty, ziaden problem zo sumom. Cize fakt len ten vstup potrebujem 10x zosilnit, nic viac.
$ cat ~/.asoundrc pcm.newdevice { type softvol slave.pcm "default" control.name "Softmaster" control.card 0 max_dB 50.0 }teda zvysenie hlasitosti by malo byt cez max_dB patch, ci ho mas zahrnuty v distribucii, to neviem. ja osobne nemozem skusit ani ci je v poslednej alse inak ako prehladanim changelogu.ale pozor aby ti to nezvysilo aj hlasitost vystupu, myslim ze ten max_dB by mal byt podla spravnosti v bloku pre mikrofon a nie v bloku pre celu zvukovku.
teda mozno takto:
$ cat ~/.asoundrc pcm.newdevice { type asym playback.pcm { type softvol slave.pcm "default" control.name "Master" control.card 0 } capture.pcm { type softvol slave.pcm "default" control.name "Maximum DB softvol mic" control.card 0 max_dB 50.0 } }fakt neviem. to druhe som zobral len z googla.
Momentalne to funguje ze ked septam tak ma uplne normalne pocut co je super. Cez ten max_dB sa to nejak neda regulovat, myslel som ze je to zisk, asi nie. Vychodzie nastavenie bolo az priliz nahlas, V "Ovládanie hlasitosti" som prepol zariadenie na Capture: ALSA PCM on front:0 (ALC662 Analog) via DMA ()PulseAudio mixer) kde je jediny "teplomer" ktory som znizil na cca 90% a teraz ti ide presne tak ako som chcel. S tym ze v sluchatkach sa stale nepocujem ale pri nahravani zvuku a v skype je to presne na maxime takze ok.
Jedina zrada je este v tom, ze ked v Skype na zalozke nastavenie zvuku dam apply, tak mi to pre ten mikrofon spravi mute. Ale ak to bude fungovat tak uz nepotrebujem nic v skype nastavovat takze snad ok. Vdaka.
Ako si si iste vsimol, tak zmeny sa prejavia po starte daneho programu takze uz nemusis robit nic. Programy si restartol a restart kompu je zbytocny, skor ho mozes na noc vypnut koli elektrike.
Ten max_Db urcuje maximalne mozne zosilnenie, aktualne zosilnenie je v mixeri ako si si vsimol, tych 50 decibelov je strop.
Tu chybu na skype nahlas jeho vyrobcovi, mozno to opravi.
PS.: je mozne nieco taketo vo viste, teda softwerovo zvysit citlivost vstupu alebo vykon vystupu?
