[Alsa-user] Get SPDIF-in sample rate

2017-07-17 Thread Denis Shulyaka
Hi, I have a CM106-based usb sound card (0d8c:0102) with SPDIF-In. My aim is to decode the compressed audio formats that may come from this source. And the first task for this is to get the original sample rate of the source to avoid any resampling. According to the CM106 datasheet, one can read
