|
|
Hi All!
I know, this is possible a beginners question. Sorry about that.
I successfully installed gentoo 2.4 on my Sun Blade 100 including Xorg.
Now I want to enable the sound. How can I do that? I want to use the
on board Soundchip (AD1881A).
Is there a step by step guide for the Sun Blade 100?
Thanks very much for helping!
Regards,
Roman |

There's no step by step guide that I'm aware of. The sound module you will want is trident under the regular OSS sound section (you won't find this under SPARC audio). Be aware that this driver does not always produce usable sound for all Blade 100 users.
As a side note, sound under 2.6 for Blade 100 users has gotten several positive reports. If you decide to go this route, use the ALI5451 ALSA module in the kernel tree (and be sure to enable oss emulation for pcm and mixer so you can use the sound device). |

Thanks, Jason! It works with Kernel 2.4. All I have to check now is the audio quality and how to disable the internal speaker;-)!

Yes ; the on board sound card works quite well on a Sunblade 100.
I use alsa modules with alsa-oss with kernel-2.6.9-rc2:
Following the alsa-guide
The kernel config file look like :
Code: | #
# Sound
#
CONFIG_SOUND=y
#
# Advanced Linux Sound Architecture
#
CONFIG_SND=m
CONFIG_SND_TIMER=m
CONFIG_SND_PCM=m
CONFIG_SND_HWDEP=m
CONFIG_SND_RAWMIDI=m
CONFIG_SND_SEQUENCER=m
CONFIG_SND_SEQ_DUMMY=m
CONFIG_SND_OSSEMUL=y
CONFIG_SND_MIXER_OSS=m
CONFIG_SND_PCM_OSS=m
CONFIG_SND_SEQUENCER_OSS=y
CONFIG_SND_BIT32_EMUL=m
#
# PCI devices
#
CONFIG_SND_AC97_CODEC=m
CONFIG_SND_ALI5451=m
|
Next ; emerge alsa-utils, alsa-oss
Code: |
emerge alsa-utils && emerge alsa-oss
|
Edit /etc/modules.d/alsa and add those 2 lines
Code: |
alias snd-card-0 snd-ali5451
alias sound-slot-0 snd-card-0
|
run
Code: |
modules-update && /etc/init.d/alsasound start
|
Check if the modules are been loaded
Code: |
nd_ali5451 27176 0
snd_ac97_codec 80388 1 snd_ali5451
snd_seq_oss 39592 0
snd_seq_midi_event 10048 1 snd_seq_oss
snd_seq 64600 4 snd_seq_oss,snd_seq_midi_event
snd_seq_device 9232 2 snd_seq_oss,snd_seq
snd_pcm_oss 64744 0
snd_pcm 109836 2 snd_ali5451,snd_pcm_oss
snd_page_alloc 14096 1 snd_pcm
snd_timer 29456 2 snd_seq,snd_pcm
snd_mixer_oss 20928 1 snd_pcm_oss
snd 59240 10 snd_ali5451,snd_ac97_codec,snd_seq_oss,snd_seq_midi_event,snd_seq,snd_seq_device,snd_pcm_oss,snd_pcm,snd_timer,snd_mixer_oss
|
Now, we have to unmute Master and Pcm :
note : I coul'd get amixer working
Finally, I can play mp3s with mpg321 only; but It plays well
From linux.debian.ports.sparc
Any other application with alsa-oss-emulation besides mpg321 and aumix
produces a terrible amount of noise, and any application that tries to
use alsa native, complains that it can't open the device. |
