Hello all, I am doing some testing with this card. Thanks for all suggestions but I have no luck yet. # lsof /dev/audio // nothing # aplay -D plughw:1 /usr/share/sounds/alsa/Front_Left.wav Playing WAVE '/usr/share/sounds/alsa/Front_Left.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono // hangs here, the syslog: Nov 8 11:04:45 teepee cannot submit datapipe for urb 2, err = -28 // same with -N and --rate switches # aplay -D plughw:1 /home/lzap/.openoffice/user/gallery/gunshot.wav Playing WAVE '/home/lzap/.openoffice/user/gallery/gunshot.wav' : Unsigned 8 bit, Rate 11025 Hz, Mono // this wont hang, but there is no sound in the output and I find this in the syslog: Nov 8 11:04:45 teepee cannot submit datapipe for urb 2, err = -28 Nov 8 11:04:45 teepee cannot submit datapipe for urb 0, err = -22 Still cannot get this working. This is sad, because this piece of hardware has unstable drivers for Windows (by usb-audio.de). I thought I will use it under Linux... -- S pozdravem / Best regards Lukas Zapletal sefredaktor / Editor-In-Chief LinuxEXPRES - opravdovy linuxovy magazin www.LinuxEXPRES.cz tel.: +420 777 003 843
