Summary: Heavily distorted audio
Description:
I have a laptop that is fine by itself, but when plugged into my docking
station I get heavily distorted audio when something plays either
directly to hw0:0 or through the OSS emulation. The problem seems to be
with sample rate conversion -- if I create my own dmix-based device that
resamples audio to 48KHz and then plays it to hw0:0, and I have an
ALSA-aware app that lets me define which device to use and set it to
that device, the audio is beautiful both on and off of the docking
station. Unfortunately, not all apps allow these settings, so things such
as RealPlayer and Flash (in Firefox) sound horrid if I'm on my docking
station, which is most of the time.
I've seen this same problem through three Linux distributions now
(Gentoo, SuSE, and Fedora Core 3) on the same laptop so I know it's an
ALSA issue (or configuration issue) and not distribution-specific.
I've hard-set the ac97 clock option in the snd-intel8x0 module to 48000
but this
doesn't help, and my clock is detected as being 48000Hz anyways. I
don't know what to do. Some people have said to point OSS apps to
/dev/adsp but apps complain it's not a valid device, and anyways pointing
to anything but /dev/dsp doesn't seem to be an option for all apps.
Besides, I'd still have the ALSA issues for apps that don't let you define
which device to use.
Following are relevant snippets of files. I'm on up-to-date Gentoo
linux using the Gentoo alsa-driver, alsa-tools, alsa-headers, alsa-lib,
and alsa-oss ebuilds, all 1.0.8. Configuration files are the defaults
(I added the extra device with a .asoundrc).
TIA,
Jeff

Will do. I'm recompiling at the moment, although I'll be unable to test it
out until later. I'll post results at that time. I'm using Gentoo
sources...alsa-lib, alsa-driver, alsa-headers are the only ones with
1.09rc2 available. Will this be enough to see if 1.09rc2 fixes my
problem, or am I going to need to build the whole alsa set from stock
sources?

Both alsa-driver and alsa-lib must be updated to the same version.
Especially, 1.0.9rc2 alsa-lib might lead to a kernel Oops with the older
alsa-driver. alsa-utils can be kept old, though.

No change with later kernels and alsa versions. Still need to define my
own device and use dmix to resample everything. Got past the
Firefox/RealPlayer/etc issues by overriding dsp0 to use dmix as well,
however.

Summary: Heavily distorted audio
Description:
I have a laptop that is fine by itself, but when plugged into my docking
station I get heavily distorted audio when something plays either
directly to hw0:0 or through the OSS emulation. The problem seems to be
with sample rate conversion -- if I create my own dmix-based device that
resamples audio to 48KHz and then plays it to hw0:0, and I have an
ALSA-aware app that lets me define which device to use and set it to
that device, the audio is beautiful both on and off of the docking
station. Unfortunately, not all apps allow these settings, so things such
as RealPlayer and Flash (in Firefox) sound horrid if I'm on my docking
station, which is most of the time.
I've seen this same problem through three Linux distributions now
(Gentoo, SuSE, and Fedora Core 3) on the same laptop so I know it's an
ALSA issue (or configuration issue) and not distribution-specific.
I've hard-set the ac97 clock option in the snd-intel8x0 module to 48000
but this
doesn't help, and my clock is detected as being 48000Hz anyways. I
don't know what to do. Some people have said to point OSS apps to
/dev/adsp but apps complain it's not a valid device, and anyways pointing
to anything but /dev/dsp doesn't seem to be an option for all apps.
Besides, I'd still have the ALSA issues for apps that don't let you define
which device to use.
Following are relevant snippets of files. I'm on up-to-date Gentoo
linux using the Gentoo alsa-driver, alsa-tools, alsa-headers, alsa-lib,
and alsa-oss ebuilds, all 1.0.8. Configuration files are the defaults
(I added the extra device with a .asoundrc).
TIA,
Jeff

Hmm, with alsa-lib 1.0.9b or later, dmix should be used by default with
this device - can you double check that disabling the .asoundrc and using
the "default" device (aplay file.wav) does not work?

jefferai - 07-15-06 15:32
----------------------------------------------------------------------
The exact model of the laptop is a Dell Inspiron 8600. I have a port
replicator for it. I only see this behavior if my speakers are connected
to the audio out jack in the port replicator; if they are connected to the
audio out in my laptop, then I do not have this problem. And again, I
only see the problem when connected to the port replicator and something
uses OSS, or uses ALSA without allowing me to select my device that forces
a sample rate conversion to 48000. I also see other behavior, like the
Headphone mixer only having an effect when plugged directly into the
laptop, not the port replicator (the PCM mixer always has an effect).
I'm using the following ~/.asoundrc:
pcm.jeff {
type plug
slave.pcm {
type dmix
ipc_key 8888
slave {

The exact model of the laptop is a Dell Inspiron 8600. I have a port
replicator for it. I only see this behavior if my speakers are connected
to the audio out jack in the port replicator; if they are connected to the
audio out in my laptop, then I do not have this problem. And again, I
only see the problem when connected to the port replicator and something
uses OSS, or uses ALSA without allowing me to select my device that forces
a sample rate conversion to 48000. I also see other behavior, like the
Headphone mixer only having an effect when plugged directly into the
laptop, not the port replicator (the PCM mixer always has an effect).
I'm using the following ~/.asoundrc:
pcm.jeff {
type plug
slave.pcm {
type dmix
ipc_key 8888
slave {
pcm "hw:0,0"
period_time 0
buffer_time 0
period_size 2048
buffer_size 32768
rate 48000
}
bindings {
0 0
1 1
}
}
}
ctl.jeff {
type hw
card {
@func getenv
vars [
ALSA_CTL_CARD
ALSA_CARD
]
default {
@func refer
name defaults.ctl.card
}
}
}
pcm.dsp0 {
type plug
slave.pcm {
type dmix
ipc_key 8888
slave {
pcm "hw:0,0"
period_time 0
buffer_time 0
period_size 2048
buffer_size 32768
rate 48000
}
bindings {
0 0
1 1
}
}
}
