Ahoj v povánoèním èase,
dostal jsem USB sluchátka a zatím se mi nepodaøilo najít zpùsob, jak je pøesvìdèit, aby hrála.
povelem:
lsusb -vv
jsem získal výpis, viz ní¾e.
Nìjak neumím najít podporu pro uvedený kodek (Texas Instruments PCM2902 Audio Codec) v jádøe, nebo jako modul.
Zkou¹el jsem èásti zvukového subsystému i podporu USB...
Nevìdìl by nìkdo, prosím, co s tím?
díky
