It works fine with the ALSA driver for analog and PCM output, even over SPDIF, but it is impossible to play AC3 sound over the SPDIF output. Only a clicking noise comes out of my speakers when I try this. The problem is, that the raw data is modified by the sound chip and not passed 1:1 to the SPDIF output. To get correct AC3 playback, the mixer and the sample rate converter have to be bypassed. This means that additionally to the bit ES_1373_SPDIF_THRU the bits ES_1373_RECEN_B and ES_1373_BYPASS_P1/ES_1373_BYPASS_P2 have to be set to make AC3 playback work. ====================================================================== ---------------------------------------------------------------------- tiwai - 08-20-2004 18:13 CEST ---------------------------------------------------------------------- It's better to check the non-audio bit in the IEC958 status controls. Does the attached patch work?
