Seems like a user application problem to me. The cs46xx driver just support a limited set of period-size configurations, that's a limitation in the HW. Then it's up to the application to handle it (I guess)
And is there any hope of any enhancement? I "need" the SPDIF of my Digifire 7.1 to be able to use the bitstreamout plugin of VDR made by Dr. Werner Fink (https://sourceforge.net/projects/bitstreamout/) because as he wrote the SPDIF out of my DVB card is not "good":
"As long as the hardware on the DVB cards are not able to put the 16bit none audio PCM data stream into a 32bit none audio S/P-DIF transport stream all receivers which uses the bit flags of the S/P-DIF transport stream for identifying none audio loose. All S/P-DIF data get from the DVB card to not have the none audio bit set. AFAIK this is a hardware bug (or better this is the information I've got from TT) ..."
But when I try the plugin I got:
Mar 29 15:15:17 localhost vdr[9090]: S/P-DIF: Period size not available: Invalid argument
Mar 29 15:15:17 localhost vdr[9090]: S/P-DIF: unable to establish BitStreamOut for none audio PCM Mar 29 15:15:17 localhost vdr[9090]: REPLAY: can't open spdif interface
I've managed to make AC3 and DTS through SPDIF work witth OGLE and Xine, I dont see any reason why it would'nt work with any other application, at least you should get further than: "S/P-DIF: Period size not available: Invalid argument" then when you've managed to open the device and write data to it maybe there will apear other unknown problems ...
