            Bug ID: 75954
                CC: lennart at poettering.net
          Assignee: pulseaudio-bugs at lists.freedesktop.org
           Summary: Alternate sample rate fails with PA_STREAM_FIX_RATE
                    flag
        QA Contact: pulseaudio-bugs at lists.freedesktop.org
          Severity: major
    Classification: Unclassified
                OS: Linux (All)
          Reporter: courmisch at gmail.com
          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.
