That's the driver I'm using but the sound is strange. In mplayer it's okay. In mpg123 it's fast and in flash animations it's reeeally fast. What can be the problem? |

kupo,
mpg123 uses the ALSA OSS interface, I'm not sure what flash uses.
I think mplayer defaults to alsa. Anway, some tests.
Play something with
| Code: | mplayer -ao alsa
mplayer -ao oss |
so we can test both interfaces.
Also post the output ofI'm assuming that the oss test sounds strange.
Do you use in kernel ALSA (you should fir this hardware) or did you | Code: | | emerge alsa-driver alsa-oss |

cat /proc/asound/cards
| Code: | 0 [I82801DBICH4 ]: ICH4 - Intel 82801DB-ICH4
Intel 82801DB-ICH4 with unknown codec at 0xe0100c00, irq 10 |
ls /dev/sound/
| Code: | | adsp audio dsp mixer |
I use the kernel drivers for alsa, I tried to compile alsa-oss before(to get aoss, so I can skype and listen to xmms at the same time) but alsa-oss failed to compile.
mplayer -ao alsa works fine(tough I needed to create a ~/.asoundrc for some reason
which contains:
| Code: | pcm.!default {
type plug
slave.pcm {
type hw
card 0
}
}
|
mplayer -ao oss is a little faster(like mpg123)
Also, I can't use alsa in Wine I can't choose it in winecfg, but I can choose oss, which sound terrible. (fast forward times 5 or something)
I didn't have these kind of problems with sound before. |

kupo,
There are several sample rates in use. CDs and PWM audio intended for analogue output from your PC use 44.1kHz.
The digital outputs (SPDI/F, also known as IEC) use 48kHz.
A common issue is playing back 44.1kHz files at 48Hz, which results in a 10% speed and frequence shift.
With alsamixer, turm off (mute) all controls with SPDI/F or IEC in their names.

Thanks for the info, but it didn't solve the problem.  |
