Hi, We recently purchased an Arturia AudioFuse USB sound card, and one thing is strange on this device. It exposes a single mixer control called 'ARTURIA Clock Selector Clock Source': $ amixer -c 4 Simple mixer control 'ARTURIA Clock Selector Clock Source',0 Capabilities: enum Items: 'ARTURIA Internal Clock' 'ARTURIA S/PDIF Clock' 'ARTURIA ADAT Clock' 'ARTURIA WORD Clock' Item0: 'ARTURIA Internal Clock' However, attempting to set the control to any value has no effect; when reading using sget the original value is always returned. $ amixer -c 4 sset 'ARTURIA Clock Selector Clock Source' 'ARTURIA S/PDIF Clock' Simple mixer control 'ARTURIA Clock Selector Clock Source',0 Capabilities: enum Items: 'ARTURIA Internal Clock' 'ARTURIA S/PDIF Clock' 'ARTURIA ADAT Clock' 'ARTURIA WORD Clock' Item0: 'ARTURIA Internal Clock' There is no error message (which there is if for instance attempting to set the control to an invalid value), it just doesn't 'stick'. By using the proprietary configuration software in [a virtual] MS Windows I can change the value and also see the new value in Linux using amixer. I've had the same problem with a completely different USB soundcard (minidsp USB streamer), so I'm suspecting it's a Linux thing rather than something specific for this soundcard. Is there something I'm missing here from a Linux point of view? /Ricard -- Ricard Wolf Wanderlöf ricardw(at)axis.com Axis Communications AB, Lund, Sweden www.axis.com Phone +46 46 272 2016 Fax +46 46 13 61 30 _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
