Dear Eric, |
| 34 |
I've modified the file DoomConfig.cfg as you indicate, and there is no sound |
| 35 |
at all when I switch to alsa. The message I get is: |
| 36 |
|
| 37 |
------------- Warnings --------------- |
| 38 |
during DOOM 3 initialization... |
| 39 |
WARNING: idPort::SendPacket: bad address type NA_BAD - ignored |
| 40 |
WARNING: sound subsystem disabled |
| 41 |
|
| 42 |
2 warnings |
| 43 |
|
| 44 |
When I specify seta s_alsa_pcm "default" in the config file, I get very noisy |
| 45 |
sounds, and the messages in the shell are: |
| 46 |
.... |
| 47 |
idAudioHardwareALSA::Write: 4096 frames overflowed and dropped |

I precise: |
| 63 |
I've got arts running using alsa output, but I specify it to suspend if |
| 64 |
inactive during 30 secondes. I tested sounds in doom3 with and without arts |
| 65 |
launched: it changes nothing. |
| 66 |
|
| 67 |
Also when running doom3, the cpu frequency is max (2.2 GHz), so I don't think |
| 68 |
that my problem would come from bad configured cpuscaling... |
| 69 |
|
| 70 |
I don't know what to do to have good perfs with good sounds. (Remember if I |
| 71 |
switch to oss backend, perfs are low and sounds are just acceptable). |
| 72 |
|

Best regards, |
