Subject: [PATCH] ALSA: hda/cs8409: Increase delay during jack detection
Git-commit: 8cd07657177006b67cc1610e4466cc75ad781c05
Patch-mainline: v5.17-rc1
References: git-fixes
Commit c8b4f0865e82 reduced delays related to cs42l42 jack
detection. However, the change was too aggressive. As a result
internal speakers on DELL Inspirion 3501 are not detected.
Increase the delay in cs42l42_run_jack_detect() a bit.
Fixes: c8b4f0865e82 ("ALSA: hda/cs8409: Remove unnecessary delays")
