Hello all,
Hopefully this is the right forum for this. This has been covered frequently in the past, but nothing I've seen so far has fixed the problem. Some sound works, some sound not so much....
This does not work:
| Code: |
# speaker-test
speaker-test 1.0.25
Playback device is default
Stream parameters are 48000Hz, S16_LE, 1 channels
Using 16 octaves of pink noise
ALSA lib pulse.c:243:(pulse_connect) PulseAudio: Unable to connect: Connection refused
Playback open error: -111,Connection refused
|
This also does not work:
| Code: |
/usr/games/bin/supertuxkart
Irrlicht Engine version 1.7.3
Linux 3.4.9-gentoo #1 SMP PREEMPT Fri Sep 21 23:50:09 Local time zone must be set-- i686
[FileManager] Data files will be fetched from: '/usr/share/games/supertuxkart/'

This works great:
| Code: |
madplay /09\ -\ Geek.mp3
|
Of course, all I really want is PCSX2 which...kinda works? I get terrible, terrible, terrible sound distortion, but I do admittedly get sound. Of course in emulation sound distortion can be it's own problem, but disturbingly I get identical pulse problems:
| Code: |
pcsx2
...
ALSA lib pcm.c:2217:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.rear
ALSA lib pcm.c:2217:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.center_lfe
ALSA lib pcm.c:2217:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.side
ALSA lib pulse.c:243:(pulse_connect) PulseAudio: Unable to connect: Connection refused
ALSA lib pulse.c:243:(pulse_connect) PulseAudio: Unable to connect: Connection refused
ALSA lib pcm_dmix.c:957:(snd_pcm_dmix_open) The dmix plugin supports only playback stream
ALSA lib pulse.c:243:(pulse_connect) PulseAudio: Unable to connect: Connection refused
ALSA lib pulse.c:243:(pulse_connect) PulseAudio: Unable to connect: Connection refused
|
What I want is for those errors to go away, and then find PCSX2's sound working perfectly (fat chance, those errors will go away and PCSX2 will probably still not work, but so is life).
This is how I mount for chroot:
| Code: |
mount -o bind /dev /mnt/gentoo-32bit/dev
mount -o bind /dev/pts /mnt/gentoo-32bit/dev/pts
mount -o bind /dev/shm /mnt/gentoo-32bit//dev/shm
mount -o bind /proc /mnt/gentoo-32bit/proc
mount -o bind /proc/bus/usb /mnt/gentoo-32bit/proc/bus/usb
mount -o bind /sys /mnt/gentoo-32bit/sys
mount -o bind /tmp /mnt/gentoo-32bit/tmp
mount -o bind /usr/portage/ /mnt/gentoo-32bit/usr/portage/
mount --bind /run /mnt/gentoo-32bit/run
|
This is roughly what I'm seeing in all the pulse in chroot howtos. Many of those howtos want to mount /var/run instead, but the friendly and always amazing support in #gentoo informs me that it's more appropriate to mount /run these days (and mounting /var/run didn't fix the problem anyways). Also, /var/lib/dbus/machine-id has matching IDs in both the host and chroot.
So what gives? Everything I read suggests the burden for getting sound to work is mount /var/run and having matching machine-ids, but this doesn't seem to be doing it for me. Thanks in advance for any help or suggestions thrown my way!  |

| I wouldn't say it's fixed, but my personal problem's resolved so this is solved. Removed the /etc/asound that redirected to Pulse. Errors still occur in terminal output, and pavucontrol on the host suggests that sound is not being routed through the host's pulse server but on the other hand it just works. I guess it's going through dmix. |
