Subject: snd_hda_intel with buffer_size set to 32768 sounds horrible. Kernel driver bug?
Date: Mon, 22 Apr 2024 13:46:16 +0100 [thread overview]
Message-ID: <CAAbCkmLGdbfsN+PXsOr8nV7rY44vvxV8y7jN1cxOr7wfsGeKwA@mail.gmail.com> (raw)
Fresh Debian Bookworm (v12) installation with alsa but no sound
server. aplay with no .asoundrc sounds great (default buffer_size is
16384). If I force the buffer_size to 32768 ([1]), then aplay sounds
horrible ([2]). Is this a kernel driver bug? (If yes, I'll log it at
https://bugzilla.kernel.org) I discovered this bug because pipewire
sets the buffer_size to 32768 hence it triggers this bug - I've logged
a bug against pipewire at [3]. Output from alsa-info at [4]. TIA.
[1] To set aplay's buffer_size to 32768, I use the following ~/.asoundrc:
pcm.!default {
type plug
slave {
pcm {
type dmix
ipc_key 1234
slave {
period_size 1024
buffer_size 32768
pcm "hw:0"
format S32_LE
}
}
}
}
