Title:
ALSA SPDIF IEC958 output no longer bit perfect (regression)
Status in alsa-driver package in Ubuntu:
Expired
Bug description:
My Intel HDA Audio chipset no longer provides bit-perfect output. When
I follow the ALSA bit perfect testing instructions ("Testing Your
Setup" at http://alsa.opensrc.org/index.php/DigitalOut) and play the
dts-encoded Norrlanda.wav using aplay, I get white noise instead of
properly decoded SPDIF output. In Hardy/Intrepid, I had bit-perfect
output, as my A/V receiver would switch to surround decoding mode and
play sound instead of white noise when I played DTS-encoded .wav files
in Amarok.
