RV on linux - what do you do for audio?

Anyone running Tweak RV on linux?

Ran into a problem where ALSA can only play one stream(it doesn't want to share the device amongst processes) , if you open a review/video window it plays audio fine, subsequent opened players have no audio.

The manual suggests using PluseAudio or JACK. We have had issues with PluseAudio using large amounts of CPU and becoming non-responsive. It goes on to say to consider using JACK with PluseAudio..

anyway was just wondering what you decided on using if you do use Tweak RV on linux.

@Grace - did not test USB soundcards recently, but i have used them in the past and latencies are usually worse because its a shared bus and you cannot guarantee latency.
@Chris - I have tested with onboard and discreet audio cards, the problem has never been the hardware, its almost always been the sound server, like pulseaudio (or in the past artsd - which i remember was a lot better, but had similar problems too).

Could it be more related to the hardware the audio software is running on, more than RV itself?

I used the Synccheck3 to do my testing (this product is discontinued, but you could get something like http://www.sync-one2.co.uk/). Using their test footage i got very good results with both dmix and the hardware cards (difference between audio & video avg: 0.16 frames max: 0.3 frames)
Im starting to roll out dmix to a few animators to see how stable it is, but i suspect i might need to spring for a bunch of these Soundblaster cards.The next tests will be on Centos-7, but i am fairly convinced that i will need to rip out pulseaudio again. I don't think this is necessarily an issue with pulseaudio, but more about rv+pluseaudio.

Response from Dan Young @ July 18, 2016, 4:05 p.m.
Heh - I can't remember exactly how the settings worked out when the golden combination went, but a fairly default PA setup shouldn't be too hard to get wangled into RV - but you'd need to check RVs settings (perhaps you have a NAS install, and could setup a global setting for it) - have you bothered reaching to Tweak's support? They were pretty helpful when I was reaching out previously with similar issues. All came good in the end.

I get the hate for LP because of avahi and systemd, but I actually think pulseaudio is kind of a step in the right direction, atleast in the grand scheme of the things he's made. \_()_/

The list of problems it aims to solve is admirable, as are its features. However, I should not need a 8-core 3GHz CPU to listen to audio without skipping and buffering. Digital devices far less powerful than this have been delivering good quality audio for some years now. As I've said elsewhere, Poettering is clearly young and full of enthusiasm. What he needs, like all young and enthusiastic folk, is a good mentor to ground him in reality. -Dan To unsubscribe from the list send a blank e-mail to mailto:studiosysadmins-discuss-request@studiosysadmins.com?subject=unsubscribe

We ended up using plain Alsa, the trick with RV to make it work 'properly' was to teak the RV setting "lock audio device" to off. Its been working like a champ since, sync's perfectly.
