Sound issue (latest stable)

Since 41.20250227 to 41.20250301.1, i have sound issues with at least wine games : sound "pops", it is garbled/chopped / metallic, it's worse with time, up to the point the issue contaminate linux apps as well (firefox, vlc...) For games, PULSE_LATENCY_MSEC=60 seems to fix the issue. If system is contaminated i have to reboot I quickly read changelogs and it seems some commit were meant to improve sound handling, but in my case it did the opposite 😦 I can provide logs if needed (As a last resort I will switch back to 41.20250216.1)

update : since PULSE_LATENCY_MSEC was fixing the issue for me, I tried to play with these parameters (so I would not need to set PULSE_LATENCY_MSEC for each game) :

context.properties = {
    default.clock.rate          = 48000
    default.clock.quantum       = 1024
    default.clock.min-quantum   = 128 # Alone or with other parameters
    default.clock.max-quantum   = 2048
}

context.properties = {
    default.clock.rate          = 48000
    default.clock.quantum       = 1024
    default.clock.min-quantum   = 128 # Alone or with other parameters
    default.clock.max-quantum   = 2048
}

and also

pulse.properties = {
    pulse.min.req = 128/48000
    pulse.default.req = 1024/48000
    pulse.min.frag = 128/48000
    pulse.default.frag = 1024/48000
    pulse.default.tlength = 1024/48000
    pulse.default.maxlength = 2048/48000
    pulse.min.quantum = 1024/48000
}

pulse.properties = {
    pulse.min.req = 128/48000
    pulse.default.req = 1024/48000
    pulse.min.frag = 128/48000
    pulse.default.frag = 1024/48000
    pulse.default.tlength = 1024/48000
    pulse.default.maxlength = 2048/48000
    pulse.min.quantum = 1024/48000
}

With no luck, the issue was still happening. With

, I noticed that when the crackling was present, another device that the one I was using as sound output was set to a different frequency rate and had a growing ERR count (alsa_output.pci-0000_01_00.1.hdmi-stereo vs alsa_output.pci-0000_06_00.0.analog-surround-21 the one I use)

context.properties = {
    default.clock.allowed-rates = [ 48000 ]
}

context.properties = {
    default.clock.allowed-rates = [ 48000 ]
}

(all of that still valid for version 41.20250314) (Note : I will also post another issue I think is unrelated)
