User471 Posted January 29, 2016 Share Posted January 29, 2016 Hi I'm posting this here although it might equally belong on the DAC forum Put a new PPA v4 PCI-E USB card in my Daphile music server the other day and I can "see" my DAC (amanero) but when I play music although Daphile does all the right things, no sound Swap to an on board USB port on the mobo, voila, music! Back to the PPA card, silence [emoji17] Even more odd I tried another couple of USB DACS at least one of which has the same amanero input chip and they worked! Go figure!! Anyone have any idea where the issue might lie - DAC, daphile or the PPA card? Cheers Sent from my D5803 using Tapatalk Link to comment
modmix Posted January 29, 2016 Share Posted January 29, 2016 What additional psu do you use? Since an OCXO clock needs much higher current than a traditional low jitter TCXO clock, it's recommended to use a 5V/2A (min.) power supply.Paul Pang Audio PPA USB Card V4 OCXO hth Ulli Link to comment
User471 Posted January 29, 2016 Author Share Posted January 29, 2016 I have a 5v/3A linear psu I plug into the jack on the back plate Sent from my D5803 using Tapatalk Link to comment
palamine Posted January 31, 2016 Share Posted January 31, 2016 I wondered if the PPA card has an issued with certain DACs myself as I was interested in purchasing a V3 but wanted to know if it would work with a Wyred 4 Sound DAC 2 DSD. I checked on the Sotm card but it looks like that card will not work with my DAC. Link to comment
Mike Rubin Posted January 31, 2016 Share Posted January 31, 2016 If the SOtM usb card is the same one that SOtM uses in its SMS-1000u, and I never have heard that the standalone one is different, it works just fine with my W4S DAC2DSD, at least when connected from an SMS-1000u.

User471 Posted January 31, 2016 Author Share Posted January 31, 2016 It seems it may be related to the os but the card is now with the DAC builder and I will report his findings Sent from my D5803 using Tapatalk Link to comment
sligolad Posted February 1, 2016 Share Posted February 1, 2016 Flashing the Amanero to latest firmware will most likely fix the problem. The NEC chips on PPA USB cards and JCat cards do not work with older Amanero Firmware through Linux. Amanero have addressed this with latest firmware.

User471 Posted February 1, 2016 Author Share Posted February 1, 2016 Cheers for that tip. Sounds like it might well be the case because I have 2 DACS with amanero chipsets and the newer one works and the older one doesn't Now, how to flash the chipset in a DAC.........???

User471 Posted March 2, 2016 Author Share Posted March 2, 2016 Doesn't look like I'm going to get any joy on this one. Does anybody know of a pcie USB card that doesn't use the NEC chip? Sent from my D5803 using Tapatalk Link to comment
panosm Posted March 2, 2016 Share Posted March 2, 2016 I have the same issue with my USB card and the new Xmos board from diyinhk. It is also a Nec chip - so you may be on to something. Link to comment
User471 Posted March 2, 2016 Author Share Posted March 2, 2016 I spoke to the guys at JCAT whose USB card also has the NEC chip. Apparently it's a bug in the chip that causes the card to report capabilities it doesn't actually have. This causes some input devices, notably the amanero, to fall over. It seems to be quite device specific. Apparently there is, or will be, a fix in the Linux kernel but clearly not in the one used by daphile at present Sent from my D5803 using Tapatalk Link to comment
