[Pkg-alsa-devel] Bug#976895: libasound2: regression (stops working): Alsa_driver: recover: pcm_status(): Broken pipe

[Thorsten Glaser]

tags 976895 + patch upstream
thanks

I’ve found that reverting a faulty upstream commit fixes this bug.

If there is no reaction within a week I intend to NMU this.

bye,
