Bug #: 48109
Summary: [regression] pulseaudio-1.99.2 doesn't like snd-pcsp
Classification: Unclassified
Product: PulseAudio
Version: unspecified
Platform: x86 (IA32)
OS/Version: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: modules
AssignedTo: [email protected]
ReportedBy: [email protected]
QAContact: [email protected]
CC: [email protected]
To reproduce: find a desktop-class machine that still has a PC speaker in
addition to a regular sound card, then build and load the snd-pcsp kernel
module. Expected results: pulseaudio should be able to use it (and it is indeed
useful for event sounds).
Actual results: pulseaudio before 1.99 worked, and 1.99.2 doesn't want to use
this device at all. Here is the relevant portion of the log:
I: [pulseaudio] card.c: Created 3 "alsa_card.platform-pcspkr"
I: [pulseaudio] alsa-util.c: cannot disable ALSA period wakeups
I: [pulseaudio] alsa-util.c: Device hw:2 doesn't support 44100 Hz, changed to
37286 Hz.
I: [pulseaudio] alsa-util.c: ALSA period wakeups were not disabled
I: [pulseaudio] alsa-sink.c: Successfully opened device hw:2.
I: [pulseaudio] alsa-sink.c: Selected mapping 'Analog Mono' (analog-mono).
I: [pulseaudio] alsa-sink.c: Successfully enabled mmap() mode.
I: [pulseaudio] alsa-sink.c: Successfully enabled timer-based scheduling mode.
E: [pulseaudio] alsa-sink.c: Failed to find any supported sample rates.
I: [pulseaudio] module.c: Loaded "module-alsa-card" (index: #7; argument:
"device_id="2" name="platform-pcspkr" card_name="alsa_card.platform-pcspkr"
namereg_fail=false tsched=yes fixed_latency_range=no ignore_dB=no
deferred_volume=yes card_properties="module-udev-detect.discovered=1"").
I: [pulseaudio] module-udev-detect.c: Card /devices/platform/pcspkr/sound/card2
(alsa_card.platform-pcspkr) module loaded.
I.e. the problem seems to be that the device only supports the weird 37286 Hz
sample rate.
