new ALSA driver on Ubuntu Studio 20 (18, 16)

[juliuspeters]

Hello,

I recently tried to install the driver on ubuntu studio (20, I tried 18 and 16 as well) and unfortunatley I failed on all 3 distributions. To be precise, I failed to install the driver on 18 and 16 but managed to run the butler. On 20, the butler failed to run but I could install the driver.

Reasons for driver failure:
Obviously there is a kernel selection routine within the c code that changes the code according to whether the kernel is newer or equal to 5.2.6. If there is a kernel newer 5.2.6, as there is in ubuntu 20, the code works ok and the driver can be compiled. If there is an older kernel, the code does not work anymore and compiling throws an error refering to the function "start clock timer" in module_timer.c. (Something with HRTIMER_MODE_ABS_SOFT).
Nevertheless, the driver works with ubuntu 20.

Reason for butler failure:
Butler has been compiled against rather old shared libraries. These include libcurl3, libssl1.0.0, libcrypto1.0.0 and probably more. These are all deprecated for quit a long time. Ubuntu 18 include the depricated ones and the new ones (libcurl4, libssl1.1 etc), but ubuntu 20 kicked out the depricated ones. Although the workaround to include libcurl3, that has been mentioned in this forum, works, this is not a solution for the other depricated shared libraries. Installing both version at least in ubuntu 20 is not easy and a pain in the ass.

I could not make both softwares work on a single machine and therefore failed to use it. I did not try other linux distributions, but even if it would work there, the butler carries the burden of being compiled against rather old pieces of software libraries.

Is there any chance that there will be an update/rework of the software soon?

I support this idea. Curl3 is no longer supported by Ubuntu 20.04. Dev team must update the source codes to solve this issue.

Any news on this? The Ubuntu 16.04 is outdated and need a refreshment because some apps need new modules and can not be installed on older versions.

Ravenna Linux driver is a sort-of Cinderella
Anyway there are Feb-2022 updates in the git repository: https://bitbucket.org/MergingTechnologi ... m/commits/

-R

P.S. I love Linux but decided to stay on Windows + ASIO as the latter driver is maintained more frequently.
