Hi, Finally I got a FIIO E10K DAC running with my Gentoo Linux and ALSA.
Alsamixer displays a volume slider for PCM only. I can play several audio sources - so far so nice. Then I installed media-plugins/alsaequal, which installs fine. I changed my .asoundrc to: ctl.equal { type equal; } pcm.plugequal { type equal; slave.pcm "plughw:0,0"; } pcm.equal { type plug; slave.pcm plugequal; } (alsamixer displays the DAC as soundcard 0 - I have deactivated the audio of the motherboard via BIOS settings) Starting for example 'alsamixer -D equal' results in an error: ALSA lib /var/tmp/portage/media-libs/alsa-lib-1.2.2/work/alsa-lib-1.2.2/src/control/control.c:1379:(snd_ctl_open_noupdate) Invalid CTL equal cannot open mixer: No such file or directory [1] 5304 exit 1 alsamixer -D equal ...seems logical to me, since I have only a volume slider in alsamixer. The FIIO establishes this USB device: Bus 005 Device 002: ID 1852:7022 GYROCOM C&C Co., LTD DigiHug USB Audio Does anyone on this list uses a FIIO E10K / E10 with Linux and got more than a simple PCM/volume slider with alsamixer ? Is there any equaliser software available, which processes the audio data instead? Is my configuration still incomplete? Cheers! Meino
