Missing master-volume on onboard soundcard?

by Michael Jarosch

Hi, there! Since approximately one year I have a new motherboard for my living- room-PC, called Biostar HiFi A88S3+. It's sound-device is a HDA-Intel with ALC892 Codec. I also use an "amplifier card" that is powered by the PCI-slot. With all of my recent equipment I've ever used it was possible to reduce noise that is produced by the digital devices in the PC: Lowering the master level did the trick. Just with the Biostar "HiFi" this doesn't seem to be possible. It always sounds like the master is open and all the noise comes quite audible through the speakers to my living room. Don't get me wrong: The master works. But it seems that lowering the volume is done by software. I wonder if this is a brand new method for manufacturers to save money or if probably the ALSA-driver is doing something wrong here? $ cat /proc/asound/cards 0 [HDMI ]: HDA-Intel - HDA ATI HDMI HDA ATI HDMI at 0xfeb64000 irq 45 1 [Generic ]: HDA-Intel - HD-Audio Generic HD-Audio Generic at 0xfeb60000 irq 16 Greets!

PreSonus 1818VSL vs Focusrite 18i20

by Ralf Mardorf

Hi, do you have experiences with PreSonus AudioBox 1818VSL and/or Focusrite Scarlett 18i20? Until now I'm using a RME HDSPe AIO and an ADA8000, but for several reasons I need an USB device. Regards, Ralf

Re: [LAU] Linux-audio-user Digest, Vol 117, Issue 33

by francois bluewin

Adding to the subject : I found on the web and in the source code of HDSPMixer 2 interesting things, namely: - despite the effective 3x16 channels, it seems the internal channels might be 3x64, or at least 64 inputs, 64 outputs and ??? playback channels - the source code shows a "playbacks_offset = 64" variable I don't really see how to use these news as the code below doesn't work. (reminder : the goal is to connect playback channels 1&2 to outputs 7&8) function set_gain () { amixer -c hw:0 cset numid=1 $1,$2,$3 > /dev/null 2>&1 } function reset_matrix () { for out in $(seq 0 63); do for inp in $(seq 0 63); do set_gain $inp $out 0 done done } reset_matrix #following lines tried 2 by 2 : set_gain 0 6 65535 #doesn't work (I tried 0 and 1 inputs as there is sound there in graphical HDSPMixer vu-meter) set_gain 1 7 65535 #doesn't work set_gain 64 6 65535 #doesn't work (64 and 65 as 1st playback channels) set_gain 65 7 65535 #doesn't work set_gain 0 128 65535 #doesn't work set_gain 1 129 65535 #doesn't work set_gain 64 128 65535 #doesn't work set_gain 65 129 65535 #doesn't work exit 0 Any idea ?

Re: [LAU] Channel routing with RME HDSPe AES without HDSPMixer

by francois bluewin

Hi, Tanks for the advice and example. Unable to find the channels numbering, I tried with the assumption that inputs are 0-15, playback 16-31 and ouptuts 0-15, but it doesn't work (there are seemingly 16 channels of each type). Checking with the graphical HDSPmixer doesn't help as it loads it's own setup when starting, so it does probably erase my "manual" setup... Does anyone know the HDSPe AES channels numbering ?

Channel routing with RME HDSPe AES without HDSPMixer

by francois bluewin

Hi All, Needing to use outputs channels 7&8 with an input on 1&2 (MPD as music server), I am unable to setup a correct .asoundrc file in order to avoid using HDSPmixer (it works well with HDSPMixer but I would have preferred to avoid using the graphic interface). My soundcard is device 0. I tried : pcm.!default { type hwplug; card 0; } ctl.!default { type hwplug; card 0; } pcm.ttable { type route; slave.pcm "default"; slave.channels 2; ttable.0.7 1; ttable.1.8 1; } ctl.ttable { type hwplug; card 0; } but it doesn't work... my ALSA knowledge is rather limited, so it's quite complicated for me. Thank you for the help ! Francois

ADAT & MIDI

by Ralf Mardorf

Hi, I'm looking for a replacement of my RME HDSPe AIO, since it's not really supported for Linux, only 2 out of 8 ADAT channels are accessible, xruns, even with too much latency, Ardour ALSA, without jack doesn't work. In addition this device must work with an iPad 2 and newer, too, so I read http://audio-mastering-studio.blogspot.de/2014/05/ios-compatible-audio-inte… and found the following device, in a price range cheaper than a RME Babyface. The device needs to provide ADAT and MIDI. I already read old Linux related posts, however, has anybody used one of the following devices with Linux? Arturia Audiofuse 599 € Focusrite Scarlett 18i8 349 € Focusrite Scarlett 18i20 489 € PreSonus AudioBox 1818VSL 399 € Could somebody recommend another device providing ADAT and MIDI less expensive than a RME Babyface? I suspect Behringer devices at least suffer from short durability. Regards, Ralf

URGENT help needed: hardware problem - HDSP card

by Iain Mott

Hi folks, I have a problem - I'm mounting an exhibition and trying to install hdsp card with a multiface card. The machine I've been given and the only one available here has one PCI slot and several other more modern types. I've installed alsa-firmware and alsa-tools from source, bu the problem is that the card is not showing up with lspci and aplay -l, nor is it showing up cat /proc/asound/cards Any suggestions please? I've looked in the BIOS and the slot is enabled. There are no other PCI type cards installed. Thank you, Iain
