MAudio MTrack 8 - Ubuntu studio, problem se vstupy

Příspěvek od alquadim » 23 pro 2015 18:00

Zdravim,

prestaly mi fungovat vstupy, resp. do Bitwig studia nejde zadny vstupni signal, i kdyz JACK ukazuje, ze jsou vstupy propojeny (viz obrazek), ale pri zkouseni napriklad MIC na vstupu 1 nic, ani se neukazuje aktivita v mixu, vsechny vystupy OK.

Odinstaloval jsem Pulseaudio, myslim, ze je navic, to by snad na to nemelo mit vliv. Nevite, v cem by to mohlo byt? Nekde v ALSA konfiguraci? Zkousel jsem i Audacity, taky nic, jen vidi vstupy (pres JACK), ale zadna aktivita na mixu.

Predtim mi to jelo bez problemu. Bude to asi nejaka malickost, ale jsem uz bezradny.

Predem diky.

Odpovim si sam:

Tak jen info, ze problem solved, jako vzdy, neznalost a pitomost. Popisu, mozna se nekomu bude hodit.

- Netreba mit ani JACK ci pulseaudio, staci ALSA.
- Kontrola, zda-li je karta nalezena a je pro ni podpora (v mem pripade card 2).

- Da se zkontrolovat i v alsamixer (F6 - vyber karty). Problem byl vsak v tom, ze zde muzete nastavit volume a mute (m), kdezto zda-li je zarizeni on ci off zde videt nelze. Proto je potreba zapnout zarizeni v amixeru. Nejdrive se podivame, jak to vypadalo s vypnutymi kanaly pro zaznam (parametr c2 znamena card 2, viz seznam vyse).
