Hey, has anyone been seeing strange behavior from this combination?
kernel 2.6.31.x rt20 + alsa 1.0.22 userland RME card (pcmcia card + multiface)
hdspmixer is not doing the right thing (does not initialize the card in a way in which playback works), it does not see the hwdep interface (or something like that) and disables metering,
[MUNCH]
I have been trying to see if I can figure _anything_ out of this...
A diff of 2.6.29 (last known working) against 2.6.31.12 reveals something that might have an influence on the problem:
in snd_hdsp_create_hwdep there are two lines added:
- hw->ops.open = snd_hdsp_hwdep_dummy_op;
Hmmm, looks like snd_hdsp_hwdep_dummy_op is not passing back the hdsp->hwdep structure to the open call at all (returning 0 is not enough from the description of the alsa api). That would explain what is happening, most probably no ioctls are found...
Am I on the right track?
Argh. I was looking at the diff backwards (DOH!). The ops.open and ops.release ioctl calls are _missing_ in the 2.6.31.12 tree.
The attached patch starts to make a difference (it restores the two missing ops in hw->ops. Once the card is recognized and the firmware is downloaded the pcmcia card + Multiface appears to be functional. Cool.
...
Now, recognizing the card is not working fully (Fedora 11 + rt kernel).
From a cold start the card is recognized but it is not fully functional,
a rmmod snd_hdsp followed by a modprobe snd_hdsp fixes that.
Here are the relevant dmesg entries:
Insert pcmcia card, multiface power cycled before that so firmware is not loaded:

So, the firmware is loaded (apparently) but hdsp_check_for_iobox does not see the Multiface. But the devices appear to be there (card #1):

Starting hdspmixer prints:

Everything seems to be there but if I start jackd it starts fine but I get no sound from the outputs.
Something has not been initialized properly. I get this at some point:
---- ALSA sound/pci/rme9652/hdsp.c:4589: Hammerfall-DSP: firmware needs to be uploaded to the card. ----
Now close jack, hdspmixer. /sbin/rmmod snd_hdsp /sbin/modprobe snd_hdsp

After that jackd is happy and the card works... Any help appreciated!! -- Fernando
