Package: libspeexdsp1 Version: 1.2~rc1.2-1 Severity: grave Tags: fixed-upstream Justification: causes non-serious data loss
On my armhf-systems (Raspberry Pi 2), the resampler library in libspeexdsp1 is introducing extreme distortion / clipping unless the input stream is strongly attenuated. I've done some additional tests confirming that: - The bug also exists upstream - The bug is corrected in latest upstream (upstream change log mentions correcting a clipping/overflow error) Additional tests: - Rebuild of libspeexdsp.so.1.5.0 - Clipping/Distortion - Rebuild of libspeexdsp.so.1.5.0, without debian patches in the resampler - Clipping/Distortion - Rebuild of libspeexdsp.so.1.5.0, but resampler.c updated to match latest speex release - Clean audio!! Some discussion also here: https://discuss.mopidy.com/t/severe-clipping-of-audio-when-using-alsa/878 Note1: This is my first time writing a debian bug report. Please change fields as necessary Note2: The libspeexdsp is default for both ALSA and pulse audio, this issue thus has a big impact on overall useability of the system for any multimedia or audio related tasks. -- System Information: Debian Release: 8.2 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable') Architecture: armhf Kernel: Linux 4.1.3-2-osmc (SMP w/2 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system)
