So the correct way is to use iecset's mnemonic mode (e.g. do iecset -c iec958:CARD=Device,DEV=0 copyright false original true) and then read back the binary values with iecset -x? I have noticed that iecset -x's output indeed changes when I do changes with iecset foo bar, did I guess that behavior correctly? Greetings Marc -- ----- Marc Haber | "I don't trust Computers.

Now we're turning around in circles. Are you trying to say that the contents of /proc/asound/cardX/stream0 will not only show the card's capabilities but also what is currently going on while there is something playing? If so, you need to word that more explicitly or somebody with less than 35 years of IT experience will not be able to understand what you're trying to say. > > I am open to suggestions for devices that will do what I want and work > > on Linux. > > I do not know what your DAT actually requires. > > But as far as I am aware, there is no USB solution that allows as much > control as your C-Media PCI card. Too bad, the machine in question will certainly be my last box with a PCI slot, so when that mainboard dies, the C-Media PCI card will die with it unless some vendor will come up with an afforable and supported PCIe-to-PCI- or USB-to-PCI-Slot interface. Additionally, the CMI8738 has caused me grief ever since. Compared with the PCI card, the USB device is rather painless. Greetings Marc -- - Marc Haber | "I don't trust Computers.

That looks like "game over" here. Alas, too bad... I am open to suggestions for devices that will do what I want and work on Linux.

That would be CARD=Device to use the USB Device, and that actually works. --rate 44100 does not seem to work. Is it possible that the USB device is only able to play back at 48 kHz so that the PC needs to resample, or can this be a driver issue that the frequency is not correctly selected? And even after successful playback with --rate 48000 and the DAT deck still being synced to the input, iecset -c iec958:CARD=Device,DEV=0 says Rate: 44100. > You might also need to mess with AES0 settings. Google for that. Google results are inconclusive, a ton of forum entries like "AES0=number fixed it for me", but nothing resembling an explanation, and nothing in the Documentation subdirectory in the kernel tree.

Whatever I do, neither "mpg321 -o alsa -a hw:1,0" nor "mpg321 -o alsa -a hw:0,2" do something different than "Can't open libao driver with device hw:1,0 (is device in use?)".

I first verified that mpg321 would happily play back to the on-board analog output and the told it to play back via the IEC958 interface, hw:0,2. That didn't work, but I also say that the optical output was not lit. I then used the text-mode alsamixer to enable the S/PDIF output which made the output light up. Am now playing back via the DAT deck. What would be the recommended application to control the ALSA mixer on a KDE Plasma 5 desktop?

[Alsa-user] How to Debug ALSA on KDE Plasma 5 (Pulseaudo in the way?)
[Reposting with correct sender, I apologize] Hi, my "big" desktop machine has a conventional audio device and an HDMI audio device on board. Additionally I have a CMI8738 based PCI Sound Card that is supposed to play audio via IEC 958 to my DAT recorder. The system is Debian unstable with KDE Plasma 5. I have pasted the output of alsa-info.sh to http://paste.debian.net/341693/ (which will hold until December 9). I am currently using pulseaudio for playback (good enough for me at the moment). However, when I configure pulseaudio via pavucontrol to play back via the CMI card's IEC958 output, the output still comes out of the card's analog outputs, and the DAT recorder doesn't even sync to any data stream. I therefore tried debugging from the bottom up. In the first step, I tried playing back via on-board analog audio via plain ALSA. List of PLAYBACK Hardware Devices card 0: CMI8738 [C-Media CMI8738], device 0: CMI8738-MC6 [C-Media PCI DAC/ADC] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: CMI8738 [C-Media CMI8738], device 1: CMI8738-MC6 [C-Media PCI 2nd DAC] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: CMI8738 [C-Media CMI8738], device 2: CMI8738-MC6 [C-Media PCI IEC958] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: SB [HDA ATI SB], device 0: ALC892 Analog [ALC892 Analog] Subdevices: 0/1 Subdevice #0: subdevice #0 card 1: SB [HDA ATI SB], device 1: ALC892 Digital [ALC892 Digital] Subdevices: 1/1 Subdevice #0: subdevice #0 card 2: HDMI [HDA ATI HDMI], device 3: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0 I configured all output devices to "Off" in pavucontrol and tried mpg321 -v -o alsa -a hw1,0. This results in "Can't open libao driver with device hw1,0 (is device in use?)". This is probably true since pulseaudio is still in use and the pulseaudio daemon is still running. When I ask pulseaudio kindly to terminate by use of the kill(1) command, some helpful other component starts a new pulseaudio daemon immediately. -- Question (1) Can I find out which process has locked a certain ALSA audio device? -- I then looked in KDE system settings for a probably checked "Enable KDE Sound System" checkbox which I remember being there from KDE 3, when I did "serious" sound on Linux for the last time. Nothing. KDE Plasma 5 does have a "Audio Hardware Setup" Tab which offers me the devices to use, pulseaudio not being one of them, and it says "Phonon VLC" as Sound Backend. I guess that phonon is somehow configured to use pulseaudio, which in turn keeps hold of my ALSA devices. -- Question (2) Which software component of my system do I reconfigure in which way to let go of my audio devices so that I can do low-level debugging of ALSA on my system to find out which software component is at fault for the digital audio malfunctions of my CMI8737 card? -- Any hints would be apprecited.

Probably, but there is no time to get accustomed with an entirely new sound server, having been through OSS, aRts, plain ALSA and pulseaudio in little more than ten years.

[Alsa-user] USB Audio with multiple Devices
Hallo, a friend has lent me one Pioneer DDJ-WeGo2. That device is a DJ controlle which has - the controller functions aside - two Audio outputs (one RCA output for the PA and one headphone) and one microphone input. The normal snd-usb-audio modul takes the device, /sys entries look like this: |[2/499]mh@fan:~$ cat /proc/asound/cards | 0 [SB ]: HDA-Intel - HDA ATI SB | HDA ATI SB at 0xfe8f4000 irq 16 | 1 [HDMI ]: HDA-Intel - HDA ATI HDMI | HDA ATI HDMI at 0xfe9bc000 irq 37 | 2 [CMI8738]: CMI8738-MC6 - C-Media CMI8738 | C-Media CMI8738 (model 55) at 0xd800, irq 22 | 3 [DDJWeGO2 ]: USB-Audio - PIONEER DDJ-WeGO2 | Pioneer PIONEER DDJ-WeGO2 at usb-:00:13.2-1.1, full speed |[3/500]mh@fan:~$ cat /proc/asound/devices | 1:: sequencer | 2: [ 1] : control | 3: [ 1- 3]: digital audio playback | 4: [ 1- 0]: hardware dependent | 5: [ 2] : control | 6: [ 2- 0]: digital audio playback | 7: [ 2- 0]: digital audio capture | 8: [ 2- 1]: digital audio playback | 9: [ 2- 2]: digital audio playback | 10: [ 2- 2]: digital audio capture | 11: [ 2- 0]: raw midi | 12: [ 2- 0]: hardware dependent | 13: [ 0] : control | 14: [ 0- 0]: digital audio playback | 15: [ 0- 0]: digital audio capture | 16: [ 0- 1]: digital audio playback | 17: [ 0- 2]: digital audio capture | 18: [ 0- 0]: hardware dependent | 19: [ 3] : control | 20: [ 3- 0]: digital audio playback | 21: [ 3- 0]: raw midi | 33:: timer Alsamixer says about the DDJ-WeGo2 Chip: USB Mixer, This sound device does not have any controls.

[Alsa-user] digital S/PDIF recording with 44.1 kHz
Hi, I have a number of DAT tapes recorded with a sampling frequency of 44.1 kHz (16 bit stereo, of course), and would like to have these recordings moved to the computer without leaving the digital domain, and if possible without resampling. On Linux. I own a Zoltrix Nightingale Pro 6 sound card with S/PDIF daughter board (showing up in lspci as 02:03.0 Multimedia audio controller: C-Media Electronics Inc CM8738 (rev 10)), which works fine on Windows. When I use this card with arecord on Linux (using arecord -Dhw:0,2 -f cd), the wav file that gets written is correctly detected by file(1) as 44.1 kHz stereo 16 bit, but is playing back about a third too fast: A 10 seconds recording plays in like 7 seconds, with the pitch shifted up appropriately as well. I can upload a test file to a web server if that's of any help. Can anybody say what is going wrong here? My OS is Debian sid, and I can experiment, and deliver any debugging information that might be useful. Greetings Marc -- - Marc Haber | I don't trust Computers.

On Linux, it seems that I can only access the analog inputs. Has anybody ever gotten this sound card to deliver the signal from the digital input to a user space application? How can I accomplish this? In response to a hint CM8738 sucks, get a decent sound card, for example one based on the Emu10K chip I bought a cheap SoundBlaster Live! card with the Digital Bracket made by Hoontech, which seems to resample the digital input to 48 kHz when used on Windows. I haven't yet tried that card on Linux. I'd appreciate any hints which way to go. Thanks in advance.
