This could be useful for a number of reasons.Update of /cvsroot/alsa/alsa-lib/test In directory sc8-pr-cvs1:/tmp/cvs-serv8451
Modified Files:
.cvsignore Makefile.am Added Files:
iecbits.c iecset.c Log Message:
added iecset program (this could be to alsa-utils after more
enhancements).
One reason it might help for is this.
1) Application outputing to the "front" device outputs sound to the spdif with PCM iec mode set.
2) Application finishes, leaving PCM iec mode set.
3) New application outputs AC3 stream with NON-AUDIO iec mode set.
4) Application finishes, leaving PCM iec mode set.
5) New application outputs AC3 stream with NON-AUDIO iec mode set.
6) Application gets killed with "kill -9 PID" leaving NON-AUDIO iec mode set.
7) Application outputing to the "front" device outputs sound, but the spdif is left in NON-AUDIO iec mode, so no sound comes out of the spdif.
From then onwards all application outputting sound will default to NON-AUDIO bit being set, when the sensible assumption would be to set PCM mode as default, and only set NON-AUDIO mode when using a device name like "iec958:AES0=0x6,AES1=0x82,AES2=0x0,AES3=0x2"
So my question is, can iecbits.c code be used to set the default iec mode back to PCM, if it has accidentally been fixed on NON-AUDIO due to the kill -9 ?
