Good people; Today I wanted to provide some good news. Some of you may recall my travails with my Schiit Bifrost USB interface under Ubuntu 12.10: but anyway, either Alsa or the Schiit or both did not successfully negotiate a bit rate change without stopping and restarting the stream. I had a lot of help from Daniel Mack with respect to patching the kernel but in the end was unable to make the combo work. The other day, I was in my neighborhood computer store and decided to buy a sound card capable of up to 192/24 out. For a lot of reasons I ended up with the Asus XONAR DX. Now I have moved my desktop machine next to the Bifrost and connected all up through a TOSLINK cable, and all is working well - sound is great, bit rate switches automatically, all is good. Three things of note here to achieve success: · S/PDIF loopback must be turned off in alsamixer or you will get no sound; · plughw is required to handle 24 bit formats (converting to S32_LE); · the card that works for me is plughw:CARD=DX,DEV=1 (DEV=0 works too but it is identified as "multichannel" by aplay). I have also disabled pulse audio for now, using the "autospawn off" setting in the pulse client configuration file /etc/pulse/client.conf I hope someone else finds this useful. One day I will play more with the USB connection on the Schiit but for now... -- Chris Hermansen · clhermansen "at" gmail "dot" com C'est ma façon de parler. ------------------------------------------------------------------------------ Everyone hates slow websites.
