A backtrace with debug symbols with winehq wine-11.5 looks like this: Backtrace: =>0 downsample [dlls/dsound/mixer.c:335] in dsound 1 resample [dlls/dsound/mixer.c:371] in dsound 2 cp_fields_resample [dlls/dsound/mixer.c:439] in dsound 3 cp_fields [dlls/dsound/mixer.c:474] in dsound 4 DSOUND_MixToTemporary [dlls/dsound/mixer.c:528] in dsound 5 DSOUND_MixInBuffer [dlls/dsound/mixer.c:599] in dsound 6 DSOUND_MixOne [dlls/dsound/mixer.c:604] in dsound 7 DSOUND_MixToPrimary [dlls/dsound/mixer.c:658] in dsound 8 DSOUND_PerformMix [dlls/dsound/mixer.c:793] in dsound 9 DSOUND_mixthread [dlls/dsound/mixer.c:832] in dsound More details in attached notes. This seems to manifest also in the tests quartz:filtergraph, winmm:mci and wmp:media. A git bisect leads to this commit: 97f3bffa60b173c43ceef6c96ed5d9a46fccef12 is the first broken commit commit 97f3bffa60b173c43ceef6c96ed5d9a46fccef12 Author: Anton Baskanov <baskanov@gmail.com> Date: Wed Jan 14 12:35:19 2026 +0700 dsound: Swap around the two nested loops in downsample. This makes the FIR array index in the inner loop to advance in fixed steps equal to fir_step. As a side effect this also eliminates the FIR step rounding. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
