I have a system running Ubuntu 9.10/xbmc and want to stream bit-perfect audio out of the SPDIF port. This I can do nicely and the system sees 44.1kHz when audio is being output. When audio stops being output, the system defaults to 48kHz and this causes a click as the DAC switches over. In fact, I managed to destroy a pair of tweeters with this click the other day (and they are expensive!!).
I also watch movies using xbmc and the audio in those is generally 48kHz, but they are played end to end and not normally as loudly, so I'd prefer the default to be 44.1 and to switch to 48kHz when necessary. If I put a rate command in the asound.conf file, I believe that will force a particular rate - I don't want to do that, just change the default frequency and still allow 44.1 and 48 to be output. Is there a way to set the default frequency to 44.1k?
