Has anyone heard of this BridgeCo DM850 chip? It seems powerful, but I'm not sure if there is any ALSA support from the company.. from the datasheet: "There are up to four Audio I/O ports, each with four I2S/I8S interfaces operating at up to 192 kHz in both I2S and I8S modes. There are up to eight SPDIF interfaces operating at up to 192 kHz." http://www.bridgeco.com/pdfs/850/adp_dm850_02_pma_chip-overv.pdf -Andrew On Thu, May 8, 2008 at 10:22 AM, Liam Girdwood <lg@xxxxxxxxxxxxxxxxxxxxxxxxxxx> wrote: > On Thu, 2008-05-08 at 15:08 +0100, Mark Brown wrote: >> On Thu, May 08, 2008 at 09:50:32AM -0400, Andrew Paprocki wrote: >> >> > Is anyone aware of a Linux/ALSA capable chip that can drive 192khz >> > I2S?
