[alsa-devel] HDSPM - Problems with SyncIn

[Andre Schramm]

Hello,

I did some tests with the SyncIn-Feature of the HDSPe cards.


[root at localhost ~]# lspci |grep Mult
01:00.0 Multimedia audio controller: Xilinx Corporation RME Hammerfall
DSP MADI (rev d2)
02:00.0 Multimedia audio controller: Xilinx Corporation RME Hammerfall
DSP MADI (rev d2)


The SyncOut of card 2:00 was plugged to the SyncIn of 1:00 and 1:00 was
put to AutoSync-mode automatically upon boot. Problem is that the amixer
output seems to be inconsistent and differs from the proc output as
well, so I'm not sure which one to trust.


[root at localhost ~]# amixer -c0 contents

  ; type=INTEGER,access=r-------,values=1,min=27000,max=207000,step=1
  : values=47999



'Preferred Sync Reference' is SyncIn, 'SYNC IN SyncCheck' says 'No
Lock', meaning no signal at all, but the 'System Sample Rate' coming
from the master card is detected with 1Hz offset. When putting the
master to 32000Hz, 31999Hz are shown and so on.


[root at localhost ~]# cat /proc/asound/card0/hdspm

Now the proc-output reports 'No TCO module detected', which is correct,
as no expansion modules where plugged to the cards. But it also says 
'Preferred Sync Reference: TCO' and 'Freq=0', where amixer said SyncIn
and 47999? Output of the master card is below.
