Priority: medium
Bug ID: 75954
CC: [email protected]
Assignee: [email protected]
Summary: Alternate sample rate fails with PA_STREAM_FIX_RATE
flag
QA Contact: [email protected]
Severity: major
Classification: Unclassified
OS: Linux (All)
Reporter: [email protected]
Hardware: x86-64 (AMD64)
Status: NEW
Version: unspecified
Component: daemon
Product: PulseAudio
SYSTEM:
HDA Intel / Realtek ALC887 card (stereo)
Linux kernel 3.13.6
Debian (Sid) on x86-64
PulseAudio 4.0 with default settings
STEPS TO REPRODUCE:
1) (re)start the PulseAudio daemon (pulseaudio -k)
-> the HDA sink input is initialized as: s16ke 2ch 44100Hz
2) play a stream at 48000kHz
-> the HDA sink input rate is changed to 48000Hz
3) stop the stream
4) play a stream at 22050Hz with PA_STREAM_FIX_RATE flag
-> the HDA sink input rate stays at 48000Hz (wrong) and the timing is totally
off, as if the card was 44100Hz. With VLC this causes continuous pitch shifts.
Note: If PA_STREAM_FIX_RATE is not used, then PulseAudio correctly reverts to
44100Hz output.
