Re: Ultralite AVB

The real fix would be to fix the firmware. As Dylan pointed out, Motus firmware does not do the necessary recovery actions in case a packet gets lost. Having an ring underrun is just one of the cases in which the host controller can detect a data loss. However there are other cases (link a crc error...

Re: How Start an Open Source project to create a replacement for RME Totalmix fx

Apparently https://github.com/agfline/RME-Fireface-UC-Drivers describes the RME protocol. So they are using usb control message for changing values in totalmix + setting the samplerate, Isochronous endpoints with 3 alternate settings for the bandwidth used by a pair of samplerates and send/receive t...

Re: How Start an Open Source project to create a replacement for RME Totalmix fx

If it is for a USB device, the device uses USB bulk endpoints for the Totalmix commmunication. These can be accessed just fine from userspace using libusb. No kernel hacking needed. And then you need to run wireshark on windows to capture the data in order to decipher the protocol used.

Alsa is limited (by the hardcoded constant SNDRV_CARDS) to a maximum of 8 alsa devices (audio+midi)

Re: Ultralite AVB

If 64 channel mode is what you're after, then you have to go into the routing tab of the web interface and set the values of "to computer" and "from computer" to a value > 32.

Re: Ultralite AVB

With the drumfix driver is it possible to change sample rate on the fly Not yet, but you can do a sudo rmmod motu; sudo modprobe motu samplerate=<new samplerate>. Second question: to use vendor mode i need to recompile the kernel or not? Yes, because the kernel developers refuse to remove the bug. ...

In their Homepage. They use JUCE as their toolkit, so easy to compile for all platforms. They even provide versions for x86 Linux and the raspberry pi.

I gave him a link to a page that fully describes how to download/compile/install BlueZ with midi support enabled. All he needed to do (provided his distribution is based on debian, and i think it is) is copy/paste the lines numbered 5-17 into a console window. But, as so many times, any advice that ...

Search for bluetoothd on your system then

Code: Select all

ldd bluetoothd
If it doesn't show a dependency on libasound2, then midi support is not compiled in.

Re: MIDI over Bluetooth in Linux?

Most likely midi support is disabled in BlueZ(which is the default). So you need to compile it with BlueZ with midi support enabled.
As an example this page describes how this is done for Ubuntu 16.04.

Re: Introducing the New RME Fireface UCX II

The trivial solution is not to buy a RME interface in the first place. The only people complaining are the ones that bought the device already. IMO there are 2 reasons why they don't support their (USB) Interfaces on Linux, either by doing the work themselfs or just handing over the necessary inform...

Re: Help with 'Merged' soundcard setup please?

Most likely reaper does only enumerate hw devices using snd_card_next instead of pcm devices using snd_device_name_hint().
Did i ever mention that i find the alsa api to be completely overengineered rubbish ?
