[PlanetCCRMA] RME 9652 - ALSA - Pulseaudio problems

Wed Apr 6 20:27:30 PDT 2011

Thanks, I followed this advice and now Pulseaudio is no longer carping. 
I will do further testing within the next week and report back in more 
detail. Meanwhile, here is the changed info in the  default.pa that I 
modeled on your example and the characteristics of the RME9652

### manually load driver for HDSP Digiface

#load-module module-alsa-sink device=hw:DSP sink_name=HDSP_PLAYBACK 
rate=48000 format=s32le tsched=0 channels=26 
channel_map=aux0,aux1,aux2,aux3,aux4,aux5,aux6,aux7,front-left,front-right,side-left,side-right,side-left,side-right,rear-left,rear-right,aux0,aux1
load-module module-alsa-sink device=hw:DSP sink_name=HDSP_PLAYBACK

#load-module module-alsa-source device=hw:DSP source_name=HDSP_CAPTURE 
rate=48000 format=s32le tsched=0 channels=26 
channel_map=aux0,aux1,aux2,aux3,aux4,aux5,aux6,aux7,front-left,front-right,side-left,side-right,side-left,side-right,rear-left,rear-right,aux0,aux1
load-module module-alsa-source device=hw:DSP source_name=HDSP_CAPTURE 
rate=48000 format=s32le tsched=0 channels=26 
channel_map=ch1,ch2,ch3,ch4,ch5,ch6,ch7,ch8,ch9,ch10,ch11,ch12,ch13,ch14,ch15,ch16,ch17,ch18,ch19,ch20,ch21,ch22,ch23,ch24,ch25,ch26

This has me wondering if support for our cards' higher sampling rate is 
as simple as using "rate=96000" and adjusting the number of channels. 
What do you think?

PS Near as I can tell the designation HDSP is also valid for my card 
(though I would feel more comfortable if there were documentation to 
refer to so that I did not have to guess). Similarly (but with the same 
level of uncertainty) the hw designation DSP seems correct for my card too.

As to the question on the list to the effect "why use pulseaudio at 
all?" -- Outside of the Music and DAW chores there are a number of 
applications (audio file players, streaming audio, etc) that also use 
the sound card and it seems perfectly sensible to have them default to 
pulseaudio (once I repair my setup).

Colin Guthrie suggested moving from Fedora to a different distribution. 
System administration chores are easier for me on Fedora in that they 
still show their Unix origins more clearly that others (e.g., Ubuntu) 
and after several decades of habituating myself to that environment 
Fedora seems a better fit for me. While I remain confident that with 
your help I can repair the audio problems that plague my system, were 
that not the case, I would be more likely to reinstall Fedora with the 
64 bit Intel kernel (for the general performance boost) than to switch 
to another 32 bit distribution on the off-chance that it might provide 
better audio support. (After all, if I could not have audio any way, 
what would I have to loose?)
