Thanks very much!! But one of my users (in Planet CCRMA) still has problems with his 9652, apparently the output labels for that card are missing and that is confirmed by looking at the source (his card works fine with the 1.0.23 hdspmixer). I applied all your patches to current git except for the version number so ignore the 1.6 version printed. I'm waiting for a backtrace from his computer about the subsequent crash.

I applied all your patches to current git except for the Indeed. There have never been labels, and now it's crashing, most likely because of dereferencing the non-existing label array. Do you mind to try this patch? Maybe it's enough. If Craig feels happy to do some remote try&error, I can sort this out with him. Right now, I'm simply assigning a stupid "1", "2" .. "64" channel naming, but maybe Craig can provide us with the correct output labels? I don't have access to a H9652, so I don't have the slightest clue how the ports are named. ;) HTH diff --git a/hdspmixer/src/HDSPMixerOutput.cxx b/hdspmixer/src/HDSPMixerOutput.cxx index 05a126c..0d8ea5c 100644 --- a/hdspmixer/src/HDSPMixerOutput.cxx +++ b/hdspmixer/src/HDSPMixerOutput.cxx @@ -262,6 +262,7 @@ void HDSPMixerOutput::setLabels() } } else { fprintf(stderr, "Unknown card type for output labels\n"); + labels_input = labels_playback = labels_madi_ss; } } ^ permalink raw reply related [flat|nested] 8+ messages in thread

Your H9652 is more or less a Digiface. The channel *count* was never a question, this is defined by the driver anyway. The remaining question simply was how to label the output destinations. >From the manual, the answer is pretty obvious: ADAT-1.1 to ADAT-1.8, followed by ADAT-2.1 to ADAT-2.8 and ADAT 3.1-to 3.8, last is S/PDIF. In double-speed mode (everything above 48kHz), the ADAT channels are cut in half, so ADAT 1.1 to ADAT 1.4, ADAT 2.1 to 2.4 and so on. S/PDIF remains unchanged as it supports higher sample rates at static channel counts (like AES/EBU). > At various times in the past when one was required to specify (e.g., > Input/Output) channels to an ALSA tool (or a program that relied on > the ALSA sound architecture) a mismatch in this number (presumably of > pcm channels) had less than desirable consequences.

Of course, this is open source. It comes without any warranty and you're free to avoid it, but to the best of my knowledge, you must not be afraid. Firstly, it's userspace, so nothing can really kill your card. Second, the whole logic is an FPGA, so it can always be flashed to a working state if something goes wrong (it cannot go wrong, as you cannot accidentally flash your card). Last but not least: the channel count has always been correct, 26 all the time, only the name array was missing. So we have this "read 26 channel names from the naming array", and it's now a question which names to write in there. I've given the answer above, but want to stress again that we're talking pure C pure userland here, so it's close to a hello world program: printf("Channel name is %s\n", name_array[channel_number]); with name_array being something like { "ADAT-1.1", "ADAT-1.2", .. } and so on. Right now, with the package prepared by Fernando, you'll simply see "1", "2", .. "26" instead of "ADAT-1.1", but this will change in a minute.

For all who care, foremost probably Fernando: $ git clone http://cluster.inf-ra.uni-jena.de/~adi/alsa-tools.git $ git checkout adi-fixes (or simply pull this branch into your local alsa-tools git repo). I've reworked the code in question. At least the label thing should be fine now, but let's wait for Craig to confirm it. Unfortunately, I won't be around on Wednesday. Maybe Fernando will prepare another test package, if not, compiling from source isn't that hard: After these two git commands, go into hdspmixer an run ./gitcompile. Then, if everythings builds correctly, run ./src/hdspmixer so see if it's working. Note that the git repo above might disappear once we have fixed all remaining issues, so if you read this mail in a couple of months from now, don't expect the URL to be still functional. ;) Cheers -- mail: adi@thur.de http://adi.thur.de PGP/GPG: key via keyserver ^ permalink raw reply [flat|nested] 8+ messages in thread
