Zdravím.

Nedávnou jsem si pořídil nový počítač. Na základní desce mám PCIe sloty a zároveň mám funkčkní TV kartu na PCI. Z tohoto důvodu jsem si pořídil redukci z PCIe na PCI (nepodporuje hot-swap). Výsledek je takový, že po zapnutí počítače mi někdy televize naběhne a někdy ne. Zatím jsem nezjistil, čím by to mohlo být způsobeno, a tak zkouším dotaz zde, jestli mě někdo někam případně popostrčí. Tak a teď ještě nacionále počítače:

• Distribuce: Linux Mint 17.3 64 bit
• Jádro: 3.19.0-32-generic
• TV karta: Hauppauge WinTV-HVR1110 DVB-T/Hybrid

A ještě přikládám nastavení v BIOSu.

V současné chvíli pro mě je otázkou loterie, jestli karta pojede nebo. Když funguje, tak běží po celou dobu bez problémů. TV mohu zapínat, vypínat libovolně jak chci, přepínat mezi kanály a vše jede. Jakmile však po zapnutí nefunguje, tak zatím nevím, jak ji přinutit "k poslušnosti". Systém ji detekuje, ale Kaffeine hlásí chybu čtení ze zařízení.

Uměl by mi někdo poradit?
