snd_emu10k1 with E-MU 1616m PCIe

snd_emu10k1 with E-MU 1616m PCIe

[tilt]

Hello!

I use the Creative E-MU 1616m PCIe:

   03:04.0 Multimedia audio controller: Creative Labs SB0400 Audigy2 Value
           Subsystem: Creative Labs Device 4007

I am on Linux kernel 3.2.4, -driver and -firmware from git;
-utils from 1.0.24.2-5 (Debian amd_64).

I have manually applied the patch from [1] and initialized
the device successfully:

[    6.315280] ALSA emufx.c:1593 EMU2 inputs on

There are irregularities & limitations, but I do have 48kHz
capture and playback.

I have two questions:

1.: I only use Dock ports, and I notice many irregularities in
DAC and ADC assignment; so I wonder: should

   /usr/local/lib/firmware/emu/micro_dock.fw

not also be loaded?

2.: I use JACK with

   input: hw:0,2 (Mutichannel Capture/PT Playback)
   output: hw:0,3 (Multichannel Playback)

One thing that I would like to fix if at all possible: I can not assign
anything
to Dock Phones L/R; instead they always repeat Dock DAC 1L/R, no matter
what I route there.

Is this a limitation of the firmware, or are the controls misleading me?

Kind regards & thanks in advance for any suggestions,
Tilman.

I see there is a test in pci/emu10k1/emu10k1_main.c, line 735f:

   snd_emu1010_fpga_read(emu, EMU_HANA_OPTION_CARDS, &reg);
   if (reg & EMU_HANA_OPTION_DOCK_OFFLINE) {
      ... the following code is NOT executed on my hardware

The flag is defined in include/sound/emu10k1.h, line 1089:

   #define EMU_HANA_OPTION_DOCK_OFFLINE    0x08
      /* Audio Dock online and FPGA not configured */

However, if instead of the above I test for

   #define EMU_HANA_OPTION_DOCK_ONLINE     0x04
      /* Audio Dock online and FPGA configured */

the test succeeds.

Does this tell me that there is no need to load a dock firmware
on my hardware? After all, dock relais went online with an audible
click, dock exposes functionality, just a bit messy.

Kind regards,
Tilman.

P.S.: Will also start working with the emutrix group to get a
hold on the mixer names & routings. I hope I can get Phones L/R
configurable with existing driver

I stand corrected, the firmware loads:

   ALSA emu10k1_main.c:739 emu1010: Loading Audio Dock Firmware
   ALSA emu10k1_main.c:686 firmware size = 0xd67c
   ALSA emu10k1_main.c:760 emu1010: EMU_HANA+DOCK_IRQ_STATUS = 0x18
   ALSA emu10k1_main.c:763 emu1010: EMU_HANA+DOCK_ID = 0x15
   ALSA emu10k1_main.c:769 emu1010: Audio Dock Firmware loaded
   ALSA emu10k1_main.c:773 Audio Dock ver: 4.2

Kind regards,
Tilman.
