As long as I know, my driver (snd-bebob) can drive it. > I've installed like you explain it on you readme file here > > https://github.com/takaswie/snd-firewire-improve You can also use DKMS package from David Henningsson's PPA. He's a developer for ALSA/Pulseaudio and familiar with my developing. This package is for trusty. https://launchpad.net/~diwic/+archive/snd-firewire-improve > And now when i switch on my firewire souncard, it's different, it seems > to "work" because i don't have flashing light as usual. > I switch on, lights flash, and then it turns blue without flashing, like > on windows. It's correct behaviour. In detail, please see these patches: http://mailman.alsa-project.org/pipermail/alsa-devel/2014-April/075885.html http://mailman.alsa-project.org/pipermail/alsa-devel/2014-April/075888.html > But now i try to make it works with audacious and it doesn't. > I try to configure audacious with ALSA out but in parameters all > firewire device listed seems don't work.... About "snd_mixer_find_selem failed" message, this behaviour is correct because my drivers don't have ALSA Control Interface. This means users cannot control internal mixer via ALSA applications such like alsamixer. For this purpose, please use ffado-dbus-server/ffado-mixer. But Ubuntu package for FFADO is a bit old. I upload the package with latest source in my PPA for trusty. https://launchpad.net/~mocchi/+archive/instruments Or you should use upstream source. http://subversion.ffado.org/wiki/InstallingFfadoFromSource If you're successful to install, you can see GUI such like in this page: http://subversion.ffado.org/wiki/MaudioBebob About "snd_pcm_hw_params_set_channels failed", this behaviour is correct to your device because AudioPhile can just playback 6ch PCM, while you try to playback 2ch PCM. There is a mismatch of channels. Instead of using "hw:2,0" PCM device, use "plughw:2,0" PCM device. This PCM device can arrange channels and solve the mismatch. > I'm not familiar with all audio stuff on Linux, maybe i've done > something wrong? > I attached you screenshot maybe it can help.... > Thanks for your reading and your future answer. No, you did correct things. Thanks for your report. If possible, would you please post your questions to alsa-devel? I believe our conversation may help to the other users. http://mailman.alsa-project.org/mailman/listinfo/alsa-devel Regards Takashi Sakamoto o-takashi@sakamocchi.jp
