[Pkg-alsa-devel] Bug#362847: libasound2: Rate converter plugin produce high-frequency noise

[Stephane Magnenat]

Package: libasound2
Version: 1.0.8-3
Severity: normal


The rate converter plugin, included in alsa and very usefull to use a
48000 Hz spdif with 44100 Hz ogg file produce high-frequency noise,
probably related to some integer overflow. This noise is only earable
when the source produces high-amplitude sound.

Here is the content of my /etc/asound.conf:

pcm.spdif48 {
        type rate
        slave {
                pcm "hw:0,4"
                rate 48000
        }
}

# Redirect to spdif48
pcm.!default {
    type plug
    slave.pcm "spdif48"     # use our new PCM here
}

# Redirect to spdif48
pcm.dsp0 {
    type plug
    slave.pcm "spdif48"     # use our new PCM here
}

Thanks,

Steph
